Two legends demonstrate how to encode data with color and size in D3 v5. The color legend maps fruit categories to distinct colors using `scaleOrdinal`, while the size legend uses `scaleSqrt` to represent numeric values with scaled circle radii. Each legend is built as a reusable component that appends SVG groups with circles and text labels, spacing them vertically and offsetting text from the markers. The code uses selection joins to update the legends’ marks and labels, with `enter()` handling new elements.

Color and Size Legends

Two customizable legends demonstrate how D3 v5 encodes data through color and size. The color legend uses `scaleOrdinal` to map fruit categories to distinct hues, while the size legend employs `scaleSqrt` to represent numerical values through circle radii. Both legends are constructed through reusable functions that bind data to SVG groups, with legends rendered as circles and text labels. The color legend applies `attr("fill", colorScale)`, while the size legend filters zero values from its ticks and spaces circles vertically.

Color and Size Legends

Two reusable legend components demonstrate color and size encoding in D3 v5. The color legend uses `scaleOrdinal` to map fruit categories to distinct colors with fixed-radius circles, while the size legend uses `scaleSqrt` to map numeric values to circle radii. Both legends render as SVG groups with tick marks, using D3’s data join pattern and `.call()` to apply each component. The size legend filters out zero values and reverses tick order, with text offset dynamically calculated from each circle’s radius.

Color and Size Legends

The example demonstrates two reusable legend components rendered in SVG: a color legend built with `d3.scaleOrdinal` mapping fruit names to categorical colors, and a size legend using `d3.scaleSqrt` for continuous numeric values with circular markers. Both legends are generated through custom functions that bind data to groups, with the color legend encoding categories via circle fill and the size legend varying circle radius. The code relies on D3 v5 selections, `.enter()`, and `.merge()` patterns to update the legends dynamically.

Color and Size Legends.js

Two reusable D3 legend components demonstrate how to encode data through color and size. The color legend uses `scaleOrdinal` to map fruit categories to distinct hues, while the size legend uses `scaleSqrt` with tick marks to represent numeric values. Both render as SVG groups with circles and text labels, updating through D3's data join pattern. The examples show how legends can be built using `selection.call` with custom functions and `merge` for enter/update transitions.

Color and Size Legends

This example demonstrates two custom legend components built with D3 v5 and rendered as SVG. A color legend uses `scaleOrdinal` to map fruit categories to distinct circle fills, while a size legend employs `scaleSqrt` with `ticks()` to encode numeric values as varying circle radii. Both legends bind data to grouped `<g>` elements, applying enter/merge/exit selections for dynamic updates. The code defines reusable functions `colorLegend` and `sizeLegend`, called via `.call()`, with text labels positioned using `textOffset`.

Color and Size Legend

Two reusable D3 legends demonstrate how to encode data through color and size. The color legend uses `d3.scaleOrdinal` to map fruit names to categorical colors, while the size legend uses `d3.scaleSqrt` to map numeric values to circle radii. Both legends are implemented as custom D3 functions that append SVG circles and text elements, using `.merge()` for efficient updates and `.exit().remove()` for cleanup. The rendering is entirely SVG-based within a single `<svg>` element, styled with CSS classes.

Color and Size Legends

Two reusable D3 legends demonstrate how to encode data through color and size. A color legend maps ordinal fruit names to distinct hues using `scaleOrdinal`, while a size legend translates a quantitative scale from 0 to 10 into circle radii via `scaleSqrt`. Both legends render as SVG groups with labeled ticks, using `selection.merge` to update existing elements efficiently. The examples show legend construction with configurable spacing, text offsets, and tick counts for flexible chart annotations.

Color and Size Legends

This example demonstrates how to create reusable color and size legends in D3 v5. It uses two custom functions, `colorLegend` and `sizeLegend`, to render ordinal color scales and square-root size scales as SVG groups. The color legend maps fruit categories to distinct fills, while the size legend displays tick values with proportional circle radii. Both legends use D3’s selection joins and scale APIs (`scaleOrdinal`, `scaleSqrt`) to update efficiently.
