This example demonstrates how to construct separate color and size legends using D3 v5. The color legend maps ordinal categories (apple, lemon, lime, orange) to distinct colors via `scaleOrdinal`, while the size legend uses `scaleSqrt` to represent numeric values with proportional circle radii. Both legends are built with reusable functions that accept `selection` and `props`, appending SVG groups with circles and text labels. The size legend filters out zero values and reverses tick order, displaying five ticks with semi-transparent black circles.

Color and Size Legends

This example demonstrates how to build both a color legend and a size legend using D3.js v5. The color legend maps ordinal categories (Apple, Lemon, Lime, Orange) to distinct colors via `scaleOrdinal`, while the size legend uses `scaleSqrt` to represent numerical values from 0 to 10 as circle radii. Both legends implement a general update pattern with `selection.merge()` for enter and exit transitions, rendering circles and text labels in SVG. The ticks for the size legend are generated using `sizeScale.ticks()`, with all elements styled via CSS classes.

Color and Size Legends

This example demonstrates how to construct separate color and size legends using D3 v5. A color legend maps ordinal categories to distinct colors, while a size legend uses a square root scale to represent numeric values with varying circle radii. The code defines reusable `colorLegend` and `sizeLegend` functions that handle tick creation, circle rendering, and text labels, then calls them with `selection.call()`. Both legends render as SVG groups with styled text and outlined circles, using `scaleOrdinal` and `scaleSqrt` from the d3 module.

Color and Size Legends

This example demonstrates how to construct custom legends for both color and size encodings in D3 v5 with SVG rendering. The color legend displays four ordinal categories—apple, lemon, lime, and orange—using d3.scaleOrdinal, while the size legend uses d3.scaleSqrt to map numeric tick values to circle radii. Both legends use reusable functions that bind data to groups, append circles and text, and position them with translate transforms.

Color and Size Legends

This example demonstrates two types of legends: a color legend for ordinal categories (apple, lemon, lime, orange) and a size legend for a square-root scale mapping values 0–10 to circle radii. Both legends use SVG groups with tick marks, rendered via D3 v6’s `scaleOrdinal` and `scaleSqrt`, and are constructed through reusable functions that append circles and labels with dynamic positioning. The color legend assigns categorical colors, while the size legend computes tick values using `sizeScale.ticks`, filters out zero, and reverses the order. Styling is applied through CSS classes for text and circle strokes.

Color and size legends

This example demonstrates two separate legends: a color legend for categorical data (plum, lemon, limes, oranges) and a size legend for quantitative data on a square-root scale. The color legend maps ordinal domains to fixed palette values, while the size legend generates five tick values using `scaleSqrt` and filters out zero. Both legends are built with reusable D3 v5 functions that append SVG groups containing circles and text, with spacing and text offsets passed as props. The rendering uses `selection.enter` and `selection.merge` to manage dynamic updates.

Color and Size Legends

This example demonstrates two custom legend components built with D3 v5: a color legend using an ordinal scale for categorical data (apple, lemon, lime, orange) and a size legend using a square-root scale for continuous numeric values. The color legend renders colored circles with text labels, while the size legend generates circles whose radii correspond to tick values, filtering out zero. Both legends are implemented as reusable functions that append SVG groups, using `scaleOrdinal` and `scaleSqrt` to map data domains to visual properties, with spacing and text offsets controlled by configuration props.

Color and Size Legends

This example demonstrates two distinct legend techniques for encoding data values. The color legend maps ordinal categories like "apple" and "lemon" to distinct colors using `d3.scaleOrdinal`. The size legend uses `d3.scaleSqrt` to translate a continuous numeric range from 0 to 10 into proportional circle radii, with tick labels derived from the scale's `.ticks()` method. Both legends are built as custom SVG components that render groups of circles and text, with the size legend's circles using a semi-transparent fill. The code relies on D3 v5's selection and merge APIs, and the `d3.select` function, to efficiently create and update the SVG elements.

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.
