This example demonstrates interactive selection and highlighting of circles in a scatter plot. The visualization renders six circles from a static dataset using D3 selections, and clicking any circle updates the application state, which re-runs the rendering function to apply a white fill and thick stroke to the selected point. It uses the `d3-rosetta` library's `unidirectionalDataFlow`, `createStateField`, and `one` utilities within a React-free, vanilla JavaScript setup, leveraging D3 v7 for DOM manipulation and event handling.
