This example demonstrates two types of legends for mapping data to visual encodings: a color legend for categorical values and a size legend for quantitative values. The color legend displays circles colored via a d3.scaleOrdinal mapping fruit names to colors, while the size legend uses d3.scaleSqrt to represent numeric ticks as varying circle radii. Both legends are rendered as SVG groups with d3-selection, using join patterns to update circle and text elements. The code is built with React and D3 v6, with the legends generated procedurally from scales rather than external data.

Color and size legends

This example demonstrates two legends for mapping data to visual encodings. A color legend uses a d3.scaleOrdinal scale to map categorical fruit names to distinct colors, while a size legend uses a d3.scaleSqrt scale to map a numeric range to circle radii. The legends are custom reusable components, created with d3.selection and appended to an SVG canvas, with each tick rendered as a group containing a circle and a text label.

Color and size legends

This example demonstrates the use of two separate legends to map data values to visual encodings. A color legend shows categorical fruit names with a d3.scaleOrdinal scale, while a size legend represents numbers from 0 to 10 with a d3.scaleSqrt scale that maps values to circle radii. The legends are rendered as SVG groups using custom reusable functions, with circles and text labels arranged vertically. The underlying data scales and spacing are defined in the JavaScript code, with fruit categories and numeric ranges specified directly.

Color and Size Legends

This example demonstrates two distinct legend types for data visualization: a color legend mapping categorical fruit names to distinct hues, and a size legend using a square-root scale for numeric values. Animated circles fade in with a two-second transition for the color legend, while the size legend renders static, semi-transparent circles. Both legends use D3 v5 selection methods, including enter/merge/exit patterns, and are built with React. The visualizations are rendered in SVG, with text labels positioned alongside each legend item.

Color Legend

This example demonstrates a versatile legend system for data visualizations, showing both a color legend for categorical data and a size legend for quantitative data. The color legend maps fruit names to distinct colors, while the size legend represents numeric tick values with proportionally scaled circles. The visualization uses D3 v5's scaleOrdinal and scaleSqrt APIs to generate the respective scales. The code constructs SVG groups for each legend item, positioning circles and text vertically with configurable spacing and offsets, and employs enter/exit animations for dynamic updates.

Color and Size Legends

This example shows two custom legends for visualizing categorical and quantitative data: a color legend mapping fruit names to distinct colors, and a size legend mapping numeric values to circle radii using d3.scaleOrdinal and d3.scaleSqrt. The legends are rendered as SVG groups with circles and text labels, positioned via transform attributes. The code uses d3-selection’s enter/merge/exit pattern to bind data and update elements, with custom functions colorLegend and sizeLegend defining the layout and spacing.

Color and size legends

This example demonstrates two custom legend components for mapping data values to visual encodings: a color legend for ordinal categories and a size legend for quantitative values. The color legend displays colored circles for fruits, while the size legend uses scaled circle radii to represent numeric values. Built with D3 v5, the code defines reusable functions `colorLegend` and `sizeLegend` that use `scaleOrdinal`, `scaleSqrt`, and selection joins to render SVG elements dynamically.

Color and Size Legends

This example demonstrates two distinct legend patterns for encoding data. A color legend uses a d3.scaleOrdinal to map categorical fruit names to colored circles, while a size legend employs d3.scaleSqrt to represent numeric values through circle radius, with tick marks generated via sizeScale.ticks. Both legends are built with D3 v5 data joins, appending SVG groups, circles, and text elements with configurable spacing and offsets, rendering in a standalone SVG canvas.
