This project contains an implementation of heatmap chart, modelled after HTML5 canvas based heatmaps, which was missing a react implementation.

The Heatmap component in this project uses the same core algorithm to paint heatmap on HTML5 canvas with slight modifications to work with React lifecycle methods.

Following screenshot shows the default heatmap view with sample data. data.js conatins the sample data in [x, y, occurances] format.

Limitations:

• Heatmap underlying canvas is currently not responsive

Refer to component/app.js on basic usage.

TBD

• Update src/config_dev.js with your canvas dimensions.
• Install node_modules dependencies using yarn
  • yarn install
• Launch the application locally using Webpack Development Server (WDS).
  • yarn start
• Alternatively, if in VSCode, launch the server using the Launch Webpack Development Server (WDS) in VSCode Debug view.
• In order to distrubute the application (S3 for example):
  • yarn build
  • copy build.js, style/*, image/*, index.html to S3 static website
