Heatmap
A Heatmap turns scattered points into a smooth gradient of color, making density and hotspots obvious at a glance. It's the go-to visualization when the story is "where is there more or less of something."
Control radius, intensity, and the color ramp, and weight points by a value column so busier locations burn hotter. Connect a Google Sheet to keep the heatmap live.
What you can do
- Adjustable intensity & radius
- Custom color gradients
- Weight-based rendering

Heatmap FAQ
How do I make a heatmap online?
Create a Heatmap site in Mapji, add your point data, tune the radius and color gradient, and publish — no code needed.
Can I weight points by value?
Yes. Map a weight column so higher-value points contribute more intensity to the heatmap.
