React Starter
This React starter example showcases a variety of heatmap configurations using @nivo/heatmap within a Storybook environment. It demonstrates different cell shapes (rectangle, square, and circle), color schemes, variable cell sizing, and custom cell components with rotated triangular paths. The heatmaps render synthetic country data generated by `@nivo/generators` `generateCountriesData`, and include custom tooltips with formatted Russian ruble values. The example also imports React and uses `storiesOf` to organize multiple heatmap variations, with styling applied through inline SVG transforms and attributes.
