This example demonstrates two custom legend components rendered with D3 v5 in a React framework. A categorical color legend maps fruit names to distinct colors using `scaleOrdinal`, while a separate size legend uses `scaleSqrt` to visualize numeric values through circle radii. Both legends animate their circles with a 1-second `transition`, and the code highlights reusable legend-building patterns through D3's data join and enter/merge/exit selections.

Color and Size Legends

This example demonstrates how to create separate color and size legends using D3 v6 in a React application, rendering with SVG. The color legend uses `d3.scaleOrdinal` to map fruit names to colors, while the size legend uses `d3.scaleSqrt` to represent numerical values through circle radii. Both legends are built with reusable functions that append groups, circles, and text elements, highlighting the pattern of entering and merging selections for dynamic updates.

Color and Size Legends

This example demonstrates two distinct legend types for data visualization: a color legend mapping categorical fruit names to distinct hues, and a size legend using a square-root scale for numeric values. Animated circles fade in with a two-second transition for the color legend, while the size legend renders static, semi-transparent circles. Both legends use D3 v5 selection methods, including enter/merge/exit patterns, and are built with React. The visualizations are rendered in SVG, with text labels positioned alongside each legend item.

Color and size legends with D3.js!

This example demonstrates how to build custom color and size legends using D3.js v5 in a React application. It shows an ordinal color scale mapping fruit names to distinct colors, alongside a square-root size scale with five ticks rendered as proportionally sized circles. The code defines reusable legend components that use selection joins with `merge()` and `exit().remove()` to manage SVG groups dynamically. Both legends render as SVG, with circles and text positioned using transform attributes and spacing parameters.

Color and Size Legends

This example demonstrates two custom D3.js legends rendered as SVG within a React application. The color legend maps categorical fruit names to distinct colors using `scaleOrdinal`, while the size legend uses `scaleSqrt` to encode numeric tick values as circle radii. Both legends are constructed with D3's data join pattern (`selectAll`, `enter`, `merge`, `exit`), displaying circles and text labels. The color legend places swatches vertically, and the size legend scales circle areas according to the square-root scale, with tick generation via `sizeScale.ticks`.

Color and size legends

This example demonstrates two types of legends for data visualization: a color legend using `scaleOrdinal` for categorical data and a size legend using `scaleSqrt` for quantitative data. The color legend displays four fruit categories with distinct colors, while the size legend shows five ticks with circle radii scaled proportionally to values. Built with React and D3 v5, the SVG rendering uses custom `colorLegend` and `sizeLegend` functions that append groups, circles, and text elements to the chart.

Color and size legend

This example demonstrates two reusable legend components: a color legend mapping ordinal categories to distinct hues, and a size legend using a square-root scale to encode numeric values through circle radii. The color legend displays fruits with colored circles, while the size legend renders circular markers with labels positioned beyond each circle. Both legends use D3 v5 scales and SVG rendering, with React-styled selection/merge patterns for dynamic updates. The size legend uses `sizeScale.ticks()` to generate evenly spaced values for its circles.

Color and Size Legends

This example demonstrates two interactive legends for mapping data to visual channels in D3 v5. A color legend uses `scaleOrdinal` to associate fruit names with distinct hues, while a size legend employs `scaleSqrt` to encode numeric values through circle radii. Both legends animate their tick marks using `transition().duration(3000)` as they enter or update. The code implements custom legend components through D3 selections and data joins, rendering SVG circles and text elements with configurable spacing and offsets.

Color and Size Legend

Two custom legend components demonstrate how to encode data through color and size. The color legend uses a D3 ordinal scale with four fruit categories, while the size legend uses a square-root scale with five tick values. Both legends are rendered as SVG groups using reusable functions that handle enter/update/exit selections. The code uses `d3.scaleOrdinal`, `d3.scaleSqrt`, and selection methods like `merge` and `attr` to position circles and text labels with consistent spacing.
