FAQ Frequently Asked Questions

What data format should I use for heatmap generation?
The tool typically accepts JSON data with key-value pairs, CSV files with labeled columns, or structured data arrays. Ensure your data has clear categories and numerical values for effective visualization.
Can I customize colors and visual appearance?
Yes, you can usually choose color schemes (hot/cold, rainbow, custom gradients), adjust intensity scaling, and modify visual elements like cell sizes, borders, and labels to match your presentation needs.
What types of data work well in heatmaps?
Heatmaps excel at showing patterns in data like website analytics, sales performance by region, survey responses, correlation matrices, and any data where you want to visualize intensity or frequency across categories.
Can I export the generated heatmaps?
Yes, most tools allow exporting heatmaps as images (PNG, SVG), interactive HTML, or sometimes PDF formats. This makes it easy to include visualizations in reports, presentations, or web applications.
Is this suitable for business intelligence and analytics?
Excellent for BI! Heatmaps quickly reveal patterns, hotspots, and trends in business data that might be missed in traditional tables or charts. They're perfect for executive dashboards and data storytelling.
