Fork of React & D3 Starter
This example loads a bird migration CSV from a GitHub Gist, parses it with D3’s `csvParse`, and displays file size, row count, and column count in a React card. It also renders a decorative SVG icon of a migration route and bird, styled dynamically via D3’s `select` to set fills and strokes. The interface shows loading and error states alongside the data summary, with the raw CSV URL listed as the source.
