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 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

A D3.js visualization demonstrates two separate legends for encoding data. The color legend maps categorical fruit names to distinct colors through an ordinal scale, displaying circles with text labels. The size legend uses a square-root scale to relate numeric values to circle radii, showing five evenly spaced ticks. Both legends are rendered as SVG groups, with circles and text positioned using translate transformations, and the size legend filters out zero values.

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 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.

Color and Size Legends

This example demonstrates how to create custom color and size legends for D3 visualizations. The color legend displays four categorical fruits using a d3.scaleOrdinal with distinct color ranges, while the size legend uses d3.scaleSqrt to map numeric values from 0 to 10 to circle radii. Both legends are built using reusable functions with enter/merge/exit patterns, rendering SVG groups with circles and text labels. The code uses D3 v5 selection methods and scales to position legend items with configurable spacing and text offsets.

Color and Size Legends

This example demonstrates how legends can visualize both ordinal color scales and quantitative size scales. A color legend maps fruit names to distinct hues using `d3.scaleOrdinal`, while a size legend translates a numeric range into varying circle diameters via `d3.scaleSqrt`. Both legends are constructed as reusable functions that append SVG `<g>` groups and circles, using D3’s selection and merge patterns to handle updates. Text labels accompany each circle, positioned relative to the circle’s radius.

Color and Size Legends

This example demonstrates how to construct separate color and size legends for a visualization. The color legend uses a categorical ordinal scale to map fruit names to distinct colors, while the size legend uses a square-root scale to map a numeric domain to circle radii. Both legends are implemented as reusable functions that append groups of circles and text labels to an SVG canvas using D3 v5 methods like `scaleOrdinal`, `scaleSqrt`, and `selection.enter().append`. Data is encoded purely through visual channels, with no underlying dataset.
