Interactive Color Legend

Interactive Color Legend

This interactive scatter plot visualizes the Iris dataset, showing petal length against sepal width with points colored by species. A React-based color legend on the right allows users to hover over species names, which highlights only the corresponding points while fading others to 20% opacity. The visualization uses d3.scaleLinear and d3.scaleOrdinal for positioning and coloring, with SVG rendering through React components that map data to circles and axis ticks. Data is loaded asynchronously via d3.csv from a GitHub gist.

Interactive Color Legend

This interactive scatter plot displays the Iris dataset, plotting petal length against sepal width with points colored by species. The color legend on the right is interactive: hovering over a species name fades all other points to 20% opacity, highlighting the selected group. The visualization uses React and D3 v6, leveraging `scaleOrdinal` for categorical colors, `scaleLinear` for axes, and SVG circles. Hovering over data points reveals tooltips via SVG `<title>` elements, while the legend’s `onMouseEnter` and `onMouseOut` handlers drive the filtering logic.

Interactive Color Legend

A scatter plot of the Iris dataset displays sepal width against petal length, with points colored by species. An interactive color legend on the right filters the visualization: hovering over a species name highlights matching points while dimming all others to 20% opacity. Built with React and D3 v5, the example uses `scaleLinear` and `scaleOrdinal`, SVG circles, and `onMouseEnter`/`onMouseOut` events to drive the hover state. The data loads via `d3.csv` from a gist.

Interactive Color Legend

This interactive scatter plot visualizes the Iris dataset, mapping petal length and sepal width across three species. A color legend categorizes data points by species, and hovering over a legend item highlights the corresponding points while fading others to 20% opacity. The visualization is built with React and D3 v5, using `scaleOrdinal` for color mapping and programmatically generated SVG components for axes and marks.

Interactive Color Legend

This interactive scatter plot visualizes the Iris dataset, plotting petal length against sepal width for three species. A color legend allows users to hover over species names, dimming all other points to highlight the selected group. The visualization uses React with d3.scaleLinear for axes, d3.scaleOrdinal for categorical colors, and d3.csv for data loading. SVG circles render the marks, while mouse events on the legend trigger state changes that adjust opacity via the fadeOpacity prop.

Interactive Color Legend

This scatter plot visualizes the Iris Dataset, showing petal length against sepal width, with points colored by species. The visualization includes an interactive color legend on the right that allows users to highlight specific species by hovering over the legend items. When a legend item is hovered, the corresponding species’ points remain at full opacity while all other points fade to 20% opacity. The chart is built using React with D3 scales (`d3.scaleLinear`, `d3.scaleOrdinal`), rendered as SVG, and includes custom axis components for tick marks and labels.

Interactive Color Legend

A scatter plot of the Iris dataset displays petal length against sepal width, with points colored by species. An interactive color legend on the right highlights a selected species by fading all other circles to 20% opacity. React manages hover state via `useState`, while D3's `scaleOrdinal` maps species to colors and `d3.csv` loads the data. The SVG visualization uses custom React components for axes, marks, and the legend, rendering with `circle` elements and D3 scales.

Interactive Color Legend

A scatter plot of the Iris dataset shows petal length against sepal width, with points colored by species. An interactive color legend on the right highlights points of a selected species while fading all others. Built with React and D3, it uses `scaleLinear` for axes, `scaleOrdinal` for colors, and SVG circles. Mouse events on the legend trigger a re-render that filters the data into separate highlighted and faded point layers.
