HeatmapAPI Client & Examples
HeatmapAPI provides a simple way to create heat map images that can be overlaid onto your own maps, dashboards, or GIS systems.
This repository contains:
- Example client-side code (HTML + JavaScript)
- A lightweight JS client wrapper for calling the HeatmapAPI service
- Documentation and usage instructions
What is a Heat Map?
A heat map is a graphical representation of two-dimensional data (X, Y, and Value) using colors. Specifically, HeatmapAPI renders the density of latitude/longitude points on a map, helping you visualize where activity is concentrated.
Why Heat Maps?
- Clarity: Raw maps often show a sea of points or polygons. Density visualization with colors makes patterns easier to understand.
- Insight: Heat maps help your users quickly spot clusters, trends, and intensity.
- Flexibility: Works with small datasets or very large ones.
Create Your Heat Map
HeatmapAPI returns your heat map as a PNG image that can be overlaid in real-time on Google Maps, Leaflet, Mapbox, or other GIS tools.
Why HeatmapAPI?
- Real-time rendering: Images are generated instantly.
- Dynamic updates: Change your data on the fly and get a new image immediately.
- Flexible data sizes: Works with small or large datasets.
- Simple integration: Just one image overlay—no need for complex vector rendering.
