This fork of the D3.js legend component experiment passes parameters into chart functions by assigning properties directly onto the functions themselves, following the reusable charts pattern. It renders an SVG with two legends: a color legend using `d3.scaleOrdinal` for fruit categories and a size legend built with `d3.scaleSqrt` for numeric ticks. The code uses `selection.call()` to invoke each component, with styles defined in CSS for tick text and circle strokes.

AI-generated description

An experiment in passing parameters into "components" by setting properties on the component functions. This is closer to the Towards Reusable Charts pattern, in that you can set state once and invoke the component elsewhere. With this approach you can't tap into the getters and setters though.

Fork of Color and Size Legends - Component Experiment

This example shows two legends rendered side-by-side in an SVG: one for ordinal color scales and one for square-root size scales. The color legend maps fruit categories to distinct fills, while the size legend displays circular marks scaled by numeric tick values. Both legends are built as reusable component functions that receive parameters via `Object.assign` properties, following the “Towards Reusable Charts” pattern. The code uses d3.v5 APIs including `scaleOrdinal`, `scaleSqrt`, and selection methods like `.call()`, `.enter()`, and `.merge()` to bind data and update the visualization.

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.

Fork of Color and Size Legends

This fork demonstrates reusable D3 legend components for both ordinal color scales and sequential size scales. Two separate legend modules render circles and labels in SVG, with colorScale mapping fruit names to colors and sizeScale using d3.scaleSqrt for proportional areas. The color legend displays four categorical items, while the size legend applies d3.ticks to generate five numeric breaks. Both components use enter/merge/exit selections to update groups dynamically.

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 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 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.

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.
