Custom Visuals

🌟 Why Use Custom Visuals?

While Power BI offers a rich set of built-in visuals like bar charts, pie charts, and line graphs, they sometimes fall short for specialized reporting needs. Custom visuals allow you to go beyond standard visualizations and provide interactivity, animation, or advanced analytics that are tailored to your business context.

From KPI indicators with thresholds, to interactive timelines and decision trees — custom visuals help users understand data faster and more intuitively.

📈 Real-World Example: Finance – Waterfall Chart for Profit Breakdown

Imagine you're a financial analyst at a multinational company presenting a quarterly profit analysis. You want to show how various factors — like product revenue, discounts, operating expenses, and taxes — contribute to the final net profit.

A standard bar chart can’t effectively show this progressive flow. Instead, you use a Waterfall Chart (available as a custom visual) which:

Visually breaks down the starting value (Gross Revenue)
Adds or subtracts intermediate values (Discounts, Costs, Overheads)
Clearly shows the impact of each component on the final Net Profit

This kind of clear step-by-step storytelling helps the CFO and stakeholders immediately spot what drives margins — no guesswork needed.

💡 Tip: Download visuals like Waterfall, Bullet Charts, or Sankey Diagrams from Microsoft AppSource. Look for the "Certified" tag to ensure performance and security compliance.

🎯 Why Use Custom Visuals?

Power BI provides a solid foundation of built-in visuals — including bar charts, pie charts, tables, and maps — that work for many common scenarios. But in certain cases, standard visuals may limit your ability to communicate insights effectively. That’s where custom visuals come in — unlocking tailored, dynamic, and sometimes industry-specific visuals for a deeper level of insight and storytelling.

📚 Enhanced Storytelling: Use visuals like Tornado charts, Heatmaps, or Infographics to highlight changes, contrasts, or key trends that wouldn't be obvious in a bar chart.
🌀 More Interactivity: Custom visuals often allow click-based filtering, drill-through, and animations — letting the user explore the data story at their own pace.
🏥 Industry-Specific Visuals: Whether you're tracking KPIs in healthcare, funnel performance in marketing, or compliance trends in finance, custom visuals are designed to speak your business language.

🏢 Business Scenario: Marketing – Interactive Funnel Chart

A digital marketing team wants to visualize how users move through their website journey: from ad impressions → to clicks → to sign-ups → to purchases.

Using a custom Funnel Chart, the team can:

Highlight where most users drop off in the journey
Use hover and click filters to see breakdowns by campaign or region
Drill into each stage to uncover why conversions dip or spike

This level of clarity wouldn’t be achievable with a simple stacked bar or pie chart — the funnel chart brings the journey to life.

💡 Tip: Choose custom visuals based on what your audience needs to understand quickly. Visuals should make the insight obvious — not require extra explanation.

🧩 Installing and Importing Custom Visuals

Custom visuals in Power BI give you the flexibility to enhance storytelling, improve interactivity, and tailor reports for specific business contexts. The process of importing them is straightforward — and once added, they behave just like native visuals.

Open Power BI Desktop.
In the Visualizations pane, click on the ellipsis (…) icon.
Select “Get more visuals” from the dropdown menu.
Browse the AppSource Marketplace or use the search bar to find the visual you need.
Click Add — the custom visual is now available in your pane and ready to use.

💼 Business Example: Finance – Bullet Chart for KPI Tracking

A financial controller needs to track monthly revenue against target benchmarks. While a bar chart shows actual numbers, it lacks context for goals and thresholds.

Using a Bullet Chart custom visual from AppSource, the controller can:

Visualize actual revenue alongside target and stretch goals
Display performance bands (e.g., poor, satisfactory, good)
Track performance in a compact format ideal for executive dashboards

This level of benchmark context is hard to convey with traditional visuals — a bullet chart offers clarity in a glance.

💡 Tip: Many custom visuals come with rich formatting options — explore the Format pane to customize labels, tooltips, interactivity, and thresholds for a polished look.

📊 Popular Custom Visuals in Power BI

✔️ Custom Visuals Best Practices

While custom visuals add richness to Power BI reports, they should be implemented with care. Below are best practices to ensure your visuals are reliable, performant, and aligned with your business needs:

🛡️ Always validate the source:
Only use visuals from reputable developers or Microsoft AppSource to avoid security risks and compatibility issues.
📌 Example: A financial institution avoided a data breach by refusing to use visuals downloaded from unverified GitHub repositories.
🔄 Check for updates:
Many visuals receive regular performance improvements and bug fixes. Always keep them updated to ensure compatibility with the latest Power BI version.
📌 Example: A custom Gantt chart visual lagged until the team updated to the latest version — which included rendering optimizations for larger datasets.
🧪 Test with your data:
Just because a visual looks good in preview doesn't mean it works well with your structure. Test it with real data to validate formatting, responsiveness, and filtering.
📌 Example: A retail analyst realized a custom sunburst chart broke down under large hierarchy depths — switching to a matrix table instead.
📉 Use minimal visuals:
Too many custom visuals can slow down report load times. Use only what enhances insight — not just decoration.
📌 Example: A sales dashboard improved load speed by replacing three custom visuals with one native chart and bookmarks.

💡 Tip: Treat custom visuals like seasoning in a dish — just enough makes it great, too much can ruin the experience.

⚠️ Limitations of Custom Visuals

While custom visuals open the door to enhanced creativity and industry-specific insights, they also come with certain limitations that should be considered — especially when building enterprise-ready dashboards.

🐌 Slower performance on large datasets:
Custom visuals often rely on external rendering engines or JavaScript libraries. In scenarios with high row counts or heavy DAX calculations, they may render slower than native visuals — affecting dashboard responsiveness.
📌 Business Example: A sales dashboard using a word cloud for analyzing 500,000 customer reviews may lag or crash during filtering, especially on slower machines or in the Power BI Service.
🔐 Security concerns if not certified:
Some third-party visuals are not Microsoft-certified. This means they might contain unknown scripts or vulnerabilities — a risk for financial or healthcare institutions dealing with sensitive data.
📌 Business Example: A healthcare firm avoids uncertified visuals when visualizing patient outcomes due to compliance with HIPAA or internal data governance policies.
🧾 Limited export capabilities:
Certain custom visuals don’t support exporting to PDF or PowerPoint, which can be a roadblock when sharing static reports with executives or external stakeholders.
📌 Business Example: A finance team using a waterfall chart from a third-party vendor cannot export monthly performance summaries for board meetings as PDFs — forcing manual screenshots.
📱 Not always mobile-optimized:
Some visuals don’t resize or respond properly on smaller screens, making mobile dashboard consumption difficult or unreliable.
📌 Business Example: A regional sales manager accessing dashboards on a tablet notices that slicers and gauges don’t align or function well — disrupting real-time decision-making on the go.

💡 Tip: Always test custom visuals thoroughly on actual datasets and devices before deploying to production — especially if user experience, export features, or mobile access are critical.

✅ Certified vs Non-Certified Visuals

Power BI offers a wide range of custom visuals through AppSource, but not all visuals are built equally. Certified visuals go through a Microsoft-led validation process to ensure they meet strict standards for quality, performance, and data security. These visuals are marked with a blue checkmark and are especially suitable for organizations with compliance requirements or sensitive workloads.

🔒 Certified Visuals:
These visuals have been tested for security vulnerabilities, performance consistency, accessibility, and API compatibility. They run in a sandboxed environment and are recommended for use in finance, healthcare, and government sectors.
📌 Business Example: A financial services firm presenting investor dashboards uses only certified bullet and KPI visuals to ensure audit compliance and data protection.
⚠️ Non-Certified Visuals:
These visuals offer greater design flexibility and unique interactivity but may pose risks in enterprise settings. They can access external libraries or scripts and may not support key features like PDF export, accessibility, or data privacy standards.
📌 Business Example: A marketing team uses a non-certified infographic visual to create a vibrant campaign dashboard — fine for internal creative review, but not for client-facing reports.

💡 Tip: For reports that require regulatory compliance or handle sensitive data, always opt for certified visuals. For creative storytelling or internal use cases, non-certified visuals can offer innovative design freedom — just test them thoroughly first.

📌 Conclusion: Unlocking the Power of Custom Visuals

Custom visuals in Power BI are more than just eye candy — they are strategic tools that elevate the storytelling and insight potential of your reports. When used wisely, they help transform complex data into compelling visual narratives that are easier to understand, engage with, and act upon.

Whether you're presenting patient outcomes in healthcare, budget analysis in finance, or sales performance in retail, custom visuals give you the flexibility to deliver data in ways that resonate with your audience.

🧭 Final Tip: Don’t overload your dashboard with visuals — be intentional. Choose custom visuals that not only look good but also enhance clarity, interactivity, and decision-making.
