This example demonstrates reusable legend components for both ordinal color scales and quantitative size scales, rendered as SVG. The color legend uses `d3.scaleOrdinal` to map fruit categories to colors, while the size legend uses `d3.scaleSqrt` to map numeric tick values to circle radii. Both legends are drawn using custom selection-based functions that append SVG groups, circles, and text elements with d3’s selection API. The code runs in d3 v5 and renders within a single SVG element.

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.

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 reusable D3.js legend components for ordinal color scales and sequential size scales. The color legend displays four fruit categories (apple, lemon, lime, orange) as colored circles, while the size legend visualizes numeric ticks from 0 to 10 as scaled circles. Both legends use D3 v5’s `scaleOrdinal` and `scaleSqrt`, with custom legend modules handling circle positioning and text offsets. The SVG rendering includes styled ticks and text, with circles given black stroke outlines for visual separation.

Fork of Color and Size Legends

This example demonstrates two reusable legend components rendered with SVG: a color legend mapping fruit categories to distinct hues, and a size legend visualizing a square-root scale from zero to ten with five labeled ticks. The color legend uses `scaleOrdinal`, while the size legend relies on `scaleSqrt` and `ticks()` to generate values. Both components are built with D3 v5’s `selection.enter` and `merge` pattern, applying circle radii, fill colors, and text offsets through `attr` and `text` operations. A video tutorial accompanies the code, showing interactive creation in the browser.

This example demonstrates reusable custom legends for both ordinal color scales and quantitative size scales, rendered as SVG groups. The color legend shows four fruit categories with distinct circle fills, while the size legend displays five tick values with proportionally sized circles. The code imports `scaleOrdinal` and `scaleSqrt` from D3 v5, and both legends are implemented as exported functions that use D3’s data join pattern (`selection.selectAll`, `.enter()`, `.merge()`) to update groups, circles, and text labels dynamically.

Fork of Color and Size Legends

This example demonstrates two common legend types: a color legend mapping ordinal fruit categories to distinct hues, and a size legend using a square-root scale to map numeric values to circle radii. The SVG renderings use d3’s selection API (`selection.selectAll`, `selection.enter`) and custom legend modules (`colorLegend`, `sizeLegend`) that generate tick groups with shapes and labels. The color legend uses `scaleOrdinal` with explicit color ranges, while the size legend calls `scaleSqrt.ticks()` to compute interval breaks, with circles stylized via CSS.

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 fork demonstrates two reusable legend components in D3 v5: a color legend for ordinal scales and a size legend for square-root scales. The color legend maps fruit categories to colored circles, while the size legend translates numeric values into varying circle radii. Both use SVG rendering and employ D3’s selection joins (`selection.selectAll`, `.enter()`, `.merge()`, `.exit()`) to bind data and update groups. Styling is applied via CSS classes for tick text and circle strokes.
