This example visualizes the Iris dataset as a scatter plot, mapping petal length and sepal width on the axes while coloring points by species. A custom interactive color legend, built with React and D3.js scaleOrdinal, is placed to the right; hovering over a legend entry fades unrelated points and highlights only the selected species. The rendering uses SVG circles generated from D3.js scaleLinear scales, with axes drawn from D3’s tick formatter.

Fork of Interactive Color Legend

This interactive scatter plot visualizes the Iris dataset, plotting petal length against sepal width, with each point colored by species. A D3 ordinal color scale maps the three species to distinct hues, while an interactive color legend highlights points of a selected species by fading the others. Built with React and D3 v5, the visualization uses SVG circles for marks, with hover events on the legend triggering opacity changes and filtering of data points.

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 example displays the classic Iris dataset as a scatter plot of petal length against sepal width, with points colored by species. Hovering over a species in the interactive color legend highlights only the corresponding points while fading the rest. Built with React and D3 v5, the visualization uses `scaleLinear` for both axes, `scaleOrdinal` for colors, and reusable axis components. The legend itself is implemented as a custom `ColorLegend` component that manages hover states and applies a configurable fade opacity to non-matching data points.

This interactive scatter plot visualizes the Iris dataset, mapping petal length against sepal width. A React component renders SVG circles colored by species using d3.scaleOrdinal, while d3.scaleLinear handles x and y positioning. Hovering over the color legend highlights points of that species and fades all others to 20% opacity. Axes are built with custom React tick components, and data loads asynchronously via d3.csv.

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.

Fork of Interactive Color Legend

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

A scatter plot of the iris dataset shows petal length against sepal width, colored by species. The visualization includes an interactive color legend; hovering over a species name in the legend highlights only the points of that species in full opacity, while all other marks fade to 20% opacity. Built with React and D3 v5, the example uses `d3.scaleLinear` and `d3.scaleOrdinal` for axes and color mapping, with SVG rendering for the marks and legend.
