npm install react-chart-doughnut
Info before start
For this type of chart you need only osY values in fact. They must be positive to show on chart. The osX is taken as labels here (can be strings). Colors are calculated according to the osY length, more data more colors.

Demo
The demo is available in module directory. To test the demo just go to demo directory in module folder and open index.html in your browser.
However, you can build the demo again with npm. To re-build the demo just go to demo directory in module folder and run command:
npm run build
This should download all packages and build the demo index.js file again. After it, you can open index.html in your browser. Should work :-)
