This interactive scatter plot visualizes the Iris Dataset, displaying petal length against sepal width with points colored by species. A color legend on the right allows hovering over a species name to highlight only its corresponding data points while fading the others to 20% opacity. The visualization is built using React with D3 scales (`d3.scaleLinear`, `d3.scaleOrdinal`) and SVG rendering. Data is fetched via `d3.csv`. The code includes custom components for axes, color legend, and marks, with hover state managed through React hooks.

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 visualizes the Iris Dataset, plotting petal length against sepal width with points colored by species. A color legend on the right highlights one species at a time when hovered, fading the remaining points to 20% opacity for emphasis. Built with React and d3.v5, it uses d3.scaleLinear for axes, d3.scaleOrdinal for colors, and d3.csv for data loading. SVG rendering is handled through React components, with hover interactions managed via onMouseEnter and onMouseOut events on legend ticks.

Interactive Color Legend

This interactive scatter plot visualizes the Iris dataset, showing petal length against sepal width, with each species distinguished by color. Hovering over the color legend highlights points from the corresponding species while dimming all others, making species comparisons intuitive. Built with React and rendered as SVG, it uses d3.scaleLinear for axes, d3.scaleOrdinal for colors, and custom React components for axes, marks, and the interactive legend. Data is loaded asynchronously from a CSV using d3.csv, with tooltips provided via SVG title elements.

Interactive Color Legend

A scatter plot of the Iris dataset maps petal length against sepal width, with each point colored by species. Hovering over a species name in the color legend dims all other points to highlight the selected group. The visualization uses React hooks to manage hover state and re-render the SVG, with scales from d3.scaleLinear and d3.scaleOrdinal. Axes and legend ticks are built from reusable React components, and the data is loaded via d3.csv.

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

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 of the Iris Dataset visualizes petal length against sepal width, with points colored by species. Hovering over a color legend entry highlights that species’s points while fading others, implemented through React state and mouse events. The visualization uses d3.scaleLinear and d3.scaleOrdinal for scales, renders SVG circles via React components, and loads CSV data with d3.csv.

Interactive Color Legend

This interactive scatter plot uses React and D3.js to visualize the Iris dataset, displaying petal length against sepal width. A color legend maps each species to a distinct color, and hovering over a legend entry highlights data points of that species while fading all others to 20% opacity. The visualization employs D3's `scaleLinear` for axes, `scaleOrdinal` for the color mapping, and SVG circles for data marks, with axes generated by custom React components from the provided files.
