This example demonstrates two reusable legend components for D3 visualizations: a color legend using an ordinal scale to map named categories to distinct colors, and a size legend using a square-root scale to encode numeric values through circle radius. The legends render as SVG groups with circles and labels, using d3.scaleOrdinal and d3.scaleSqrt. Both components employ the enter/merge/exit pattern to update efficiently, with a video link provided in the README.

Color and Size Legends

This example demonstrates two reusable legend components for D3 visualizations. The color legend maps a categorical color scale to labeled circles, while the size legend uses a square-root scale to vary circle radii across numeric ticks. Both legends are implemented as custom D3 functions (`colorLegend` and `sizeLegend`) that append SVG groups with circles and text. The code uses `d3.scaleOrdinal` and `d3.scaleSqrt` to define the scales, and the rendering is done with SVG elements on a 960×500 canvas.

Color and Size Legends

This example demonstrates two reusable legend components for D3 visualizations: a color legend mapping ordinal categories (apple, lemon, lime, orange) to distinct hues, and a size legend using a square-root scale to represent numeric values. The color legend renders colored circles with labels, while the size legend positions circles of varying radii with tick marks. Both use SVG groups and the `selection.merge` pattern for enter-update-exit handling, with styling applied via the `.tick` class.

Color and Size Legend

This example demonstrates two reusable D3 legend components: an ordinal color legend and a square-root size legend, rendered side-by-side in an SVG. The color legend maps five categorical domain values to a spectral color palette, with labeled circles spaced vertically, while the size legend encodes numeric ticks with scaled circle radii and translucent fills. Both use D3 v5 data joins (`selection.enter`, `.merge`) and scales (`scaleOrdinal`, `scaleSqrt`), and are invoked via the `.call()` method with custom props for radius, spacing, and text offset.

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 built with D3 v5: a color legend using `scaleOrdinal` for categorical data and a size legend using `scaleSqrt` for quantitative data. The color legend renders colored circles with domain labels, while the size legend displays circles scaled proportionally to tick values with corresponding text offsets. Both legends are implemented as modular functions that append SVG groups and circles, using D3’s selection and merge pattern to handle updates efficiently.

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 legend styles for D3 visualizations: a color legend mapping ordinal categories to colors, and a size legend mapping a square-root scale to circle radii. The color legend displays four fruit labels next to colored circles, while the size legend shows five tick values with circles whose areas scale with the data. Both legends are built as reusable SVG components using D3's selection API, with `scaleOrdinal` and `scaleSqrt` defining the mappings. The code uses `.call()` to invoke the legend functions and `merge()` to handle updates efficiently.

Color and Size Legends

This example demonstrates two reusable D3.js legend components: a color legend for ordinal scales and a size legend for quantitative scales. The color legend displays four fruit categories with distinct colors, while the size legend uses a square-root scale with four reversed ticks. Both legends are implemented as custom D3.js functions that accept an SVG group and configuration props, using d3.scaleOrdinal and d3.scaleSqrt. The SVG rendering includes labeled circles with custom spacing and text offsets, styled via CSS with sans-serif fonts and black stroke outlines.
