This interactive scatter plot visualizes the Iris dataset, mapping petal length against sepal width, with each point colored by species. Hovering over a species in the color legend highlights only points of that species by increasing their opacity while dimming others. The visualization uses React with D3 scales, including `d3.scaleLinear` for axes and `d3.scaleOrdinal` for colors. It fetches data via `d3.csv` and renders all marks and the legend as SVG circles.

Fork of Interactive Color Legend

This interactive scatter plot shows the Iris dataset, mapping petal length and sepal width while coloring points by species. A color legend to the right of the plot allows hovering over a species name to highlight the corresponding points and fade all others. The visualization is built with React and D3's scaleLinear, scaleOrdinal, and csv loading functions, rendering SVG marks and axes. Hover interactions are managed through React state, with fading applied by adjusting opacity on both the legend entries and data circles.

This interactive scatter plot visualizes the Iris dataset, displaying petal length against sepal width with points colored by species. The visualization uses react and d3.scaleOrdinal for coloring, d3.scaleLinear for positioning, and SVG for rendering. Hovering over a species in the color legend highlights only those data points, while non-matching points fade to 20% opacity, implemented through React's useState hook for hover state management.

This interactive scatter plot visualizes the Iris dataset, plotting petal length against sepal width and coloring each point by species. Hovering over a species in the color legend filters the visible marks to that category while dimming the rest, implemented through React state and mouse events. The visualization uses d3.scaleLinear for axes, d3.scaleOrdinal for color mapping, and d3.csv for data loading, with all elements rendered as SVG within a React component structure.

This interactive scatter plot visualizes the Iris dataset with petal length on the x-axis and sepal width on the y-axis, colored by species. It uses D3 scales for positioning and color encoding, with React components rendering SVG circles and axes. Hovering over a species in the color legend highlights only the corresponding data points while dimming the rest, leveraging D3's scaleOrdinal and React state for interactivity. The data is loaded via d3.csv from a remote Gist.

This interactive scatter plot visualizes the Iris dataset, displaying petal length against sepal width, with each species colored and listed in a hoverable color legend. Hovering over a species name in the legend fades non-matching points to a low opacity while highlighting the corresponding data. Built with React and D3 v5, it uses `scaleLinear` and `scaleOrdinal` for positioning and color mapping, with SVG rendering for all marks and interactive legend elements. The data is loaded asynchronously from a CSV file using D3’s `csv` function.

This interactive scatter plot of the Iris dataset maps petal length against sepal width, with each species represented by a distinct color. Users can hover over the color legend to highlight points of a particular species while dimming all others, using React state for hover tracking. The visualization uses d3.scaleLinear, d3.scaleOrdinal, and d3.csv for data loading and scaling, with SVG rendering through React components for axes, marks, and the interactive legend.

Fork of Interactive Color Legend

This interactive scatter plot visualizes the Iris dataset, showing petal length against sepal width with points colored by species. Hovering over a species label in the color legend fades non-matching points to 20% opacity while highlighting the selected group. Built with React and D3 v5, the code uses `scaleLinear`, `scaleOrdinal`, and `csv` for data loading, rendering SVG circles and axes via reusable components. The color legend triggers hover events through React state to dynamically filter and emphasize data points.
