This example demonstrates two reusable legend components rendered side by side in an SVG: a color legend using an ordinal scale mapping fruit names to distinct colors, and a size legend built from a square-root scale with circular marks sized proportionally to tick values. Both legends use D3 v5’s selection joins to update enter and exit states. The color legend calls `scaleOrdinal`. The size legend uses `scaleSqrt.ticks()` for tick generation.

Color and Size Legends

This example demonstrates two reusable legend components rendered as SVG: a color legend using an ordinal scale mapping fruit categories to distinct colors, and a size legend using a square-root scale to encode numeric values through circle area. The color legend displays evenly spaced colored circles with labels, while the size legend computes ticks via `sizeScale.ticks()`, filters out zero, and reverses their order. Both components are built with D3 v5, using `selection.merge()`, `enter()`, and `exit()` patterns to handle dynamic updates, and accept configuration props such as spacing, text offset, and circle styling.

Color and Size Legends

This example demonstrates two reusable legend components rendered with D3 v5: a color legend for ordinal scales and a size legend for square-root scales. The color legend maps fruit categories to distinct colors, while the size legend visualizes numeric values using scaled circle radii. Both components use D3 selections and data joins to update legends dynamically. The code relies on `scaleOrdinal`, `scaleSqrt`, `scale.ticks`, and custom group elements with SVG circles and text labels, styled via CSS classes.

Color and Size Legends

This example demonstrates two reusable legend components rendered as SVG: a color legend for ordinal scales and a size legend for quantitative scales. The color legend displays fruit categories (apple, lemon, lime, orange) as colored circles, while the size legend uses a square-root scale to map numeric values to circle radii. Both legends are built with D3 v5, using `scaleOrdinal` and `scaleSqrt`, with custom functions that handle enter/merge/exit selections. The code imports `select` from D3 and renders the legends via the `call` method.

Color and Size Legends

This example demonstrates two reusable legend components rendered with SVG: a color legend for ordinal data and a size legend for quantitative data. The color legend maps fruit names to distinct colors, while the size legend uses `d3.scaleSqrt` to encode numeric values through circle radii. Both legends use D3 v5’s data join pattern, with Enter and merge selections to update ticks. The size legend calculates tick values via `scale.ticks` and filters out zero.

Color and Size Legends

The example demonstrates two reusable legend components rendered as SVG: a color legend mapping fruit names to ordinal colors, and a size legend using a square-root scale with circular marks. Both legends are built with D3 v5, using `scaleOrdinal`, `scaleSqrt`, data joins with `selection.enter()`, and merge operations to update tick groups. The color legend draws lines labeled with fruit names, while the size legend displays circles sized by the scale with tick text offset by radius. Styling is applied via CSS classes for tick text and circle strokes.

Color and Size Legends

This example demonstrates two custom legend components rendered as SVG: a color legend using a d3 ordinal scale mapping fruit names to colors, and a size legend using a d3 square-root scale mapping numeric values to circle radii. The color legend places equally sized circles with labels, while the size legend shows varying circle sizes with tick values generated by `sizeScale.ticks()`. Both rely on D3’s data join pattern (`selectAll().data().enter()`) with explicit `spacing` and `textOffset` props for layout, and are called via the `selection.call()` method.

Colour and Size Legends

This example demonstrates two reusable legend components rendered as SVG: a color legend displaying an ordinal scale with fruit names and assigned colors, and a size legend using a square-root scale to map numeric values to circle radii. The code uses D3 v5 APIs including `scaleOrdinal`, `scaleSqrt`, and `selection.call` to bind the legend functions. Each legend updates through data joins, with circles and text elements positioned using transform attributes and spacing constants.

Color and Size Legends

This example demonstrates two reusable legend components in D3 v5: a color legend for ordinal scales and a size legend for quantitative scales. The color legend maps fruit names to distinct colors using `scaleOrdinal`, while the size legend uses `scaleSqrt` to represent numeric ticks as proportional circle radii. Both legends are rendered as SVG groups with circles and text, using `.call()` to apply the component functions. The size legend filters out zero values and reverses tick order to display larger circles first.
