This visualization displays a collection of black circles arranged in a pictogram of the Spotify logo, with a single white circle highlighted upon selection. It uses React to manage state and a D3 `scaleLinear` to map the logo’s coordinate system to the container size. The `renderCircles.js` file binds data to circles, updating fill, stroke, and click interactions, while `useContainerDimensions` leverages a `ResizeObserver` to adapt the SVG dimensions responsively.
