This example demonstrates two reusable legend components created with D3.js v5: a color legend mapping categorical names to colored circles, and a size legend using a square-root scale to encode numeric values through circle radius. The SVG output renders the legends with custom styling, including font size, spacing, and semi-transparent fill colors. The code defines modular JavaScript functions, `colorLegend` and `sizeLegend`, which are called with configuration objects to dynamically generate the legend groups, circles, and text labels based on the specified scale and tick values.

Fork of 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 values. The SVG rendering shows each legend as a series of labeled circles, with the size legend filtering out zero values and reversing tick order. The code defines exportable functions `colorLegend` and `sizeLegend` that accept scales and layout props, using D3’s data joins and `selection.merge` for enter-update-exit patterns. Styling comes from CSS classes, with the size legend using a semi-transparent circle fill.

Fork of Color and Size Legends2

This example demonstrates two reusable legend components for D3 v5: a color legend using an ordinal scale mapping fruit names to colors, and a size legend using a square-root scale with five ticks. Both render as SVG groups with circles and text labels, positioned via transforms. The colorLegend component encodes categorical data with colored circles, while the sizeLegend uses scaled circle radii and offsets text based on each value’s radius. The code imports `scaleOrdinal` and `scaleSqrt` from D3, and uses selection joins to update or remove legend items dynamically.

Fork of Color and Size Legends

This example demonstrates two reusable legend components rendered side-by-side: a color legend for ordinal data (apple, lemon, lime, orange, kivi) and a size legend for a square-root scale ranging from 0 to 10. The color legend displays colored circles with labels, while the size legend uses semi-transparent black circles of varying radii. Both are built with D3 v5’s `scaleOrdinal`, `scaleSqrt`, and `selection.call()`, generating SVG groups with circle and text elements styled via CSS classes.

Fork of Color and Size Legends

This example demonstrates two reusable legend components rendered as SVG: a color legend for ordinal data and a size legend for quantitative data. The color legend displays circles for apple, lemon, lime, and orange, while the size legend uses a square-root scale with five ticks. Both use D3 v5’s `scaleOrdinal` and `scaleSqrt`, with `selection.merge` to update entries efficiently. The components are defined as JavaScript modules and called via `.call()`, with styling applied through CSS classes.

Fork of Color and Size Legends

This example demonstrates two reusable legend components for D3 visualizations: a color legend showing ordinal categories (apple, lemon, lime, orange) with distinct hues, and a size legend using `scaleSqrt` to map numeric values to circle radii. The code exports `colorLegend` and `sizeLegend` as JavaScript modules, using `selection.selectAll` and `groups.enter()` to bind data, append SVG circles and text, and handle updates. The legends are rendered with d3.v5, with text styling defined in an external stylesheet.

Fork of Color and Size Legends

This fork of the color and size legends example displays separate reusable legend components, each implemented as a D3.js module. The color legend maps a categorical ordinal scale to colored circles, while the size legend (present but commented out) maps a quantitative square-root scale to varying circle radii. Both use D3 v5’s selection API and `scaleOrdinal`/`scaleSqrt` with an SVG `g`-based tick layout, with text labels offset from the shapes.

Fork of Color and Size Legends

This example demonstrates reusable legend components for both ordinal color scales and quantitative size scales. The color legend renders colored circles with labels for fruit categories, while the size legend displays circles scaled by magnitude using a square-root scale. Both legends are implemented as custom D3 functions that bind data to SVG groups, using `selection.enter()` and `selection.merge()` for updates. The code utilizes `d3.scaleOrdinal`, `d3.scaleSqrt`, and `scale.ticks()` to generate tick values for the size legend.

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.
