A fork of the "Interactive Color Legend" visualization, this scatter plot displays the classic Iris Dataset, plotting sepal length against petal length. The visualization uses D3.js, specifically `scaleLinear`, `scaleOrdinal`, and `schemeCategory10` for color mapping. Hovering over a color legend item highlights the corresponding data points in the plot, while dimming others, using a `selection.join` pattern. The interaction is managed through state handling with `setHoveredValue` and `hoveredValue`, showcasing an effective way to explore categorical data.
