This example demonstrates two distinct legend types for different data encodings: a color legend with categorical swatches for fruits and a size legend with scaled circles for numeric values. Built with D3 v5, it renders SVG elements using reusable functions `colorLegend` and `sizeLegend`. The color legend uses `scaleOrdinal` with discrete colors, while the size legend employs `scaleSqrt` and generates ticks via `sizeScale.ticks()`. Both legends position circles and text labels with explicit spacing and offset values.

Color and Size Legends

This example demonstrates two distinct legend types: a color legend with ordinal categories for fruits and a size legend with a square-root scale mapping numeric values to circle radii. Using D3 v5, it renders SVG circles and text labels, with the color legend employing `scaleOrdinal` and the size legend using `scaleSqrt` with tick generation. The size legend positions circles based on cumulative radius sums with spacing, while both legends use reusable functions (`colorLegend` and `sizeLegend`) called via D3’s selection `.call()` pattern.

Color and Size Legends

This example demonstrates two types of legends built with D3 v5: a color legend for an ordinal scale and a size legend for a square-root scale. The color legend maps fruit names to distinct colors, while the size legend uses `sizeScale.ticks` to generate five circle radii. Both legends are rendered as SVG groups, with circles and text positioned using `spacing` and `textOffset` parameters from custom `colorLegend` and `sizeLegend` modules.

Color and Size Legends

This example demonstrates two methods for building interactive legends in D3.js v5: a categorical color legend and a quantitative size legend. The color legend uses `scaleOrdinal` to map fruit names to distinct colors, while the size legend uses `scaleSqrt` to map a numeric range to circle radii. Both legends are rendered as SVG groups with circles and text labels, positioned via `translate` transforms. The reusable legend functions (`colorLegend` and `sizeLegend`) accept configuration objects specifying spacing, circle radius, and tick counts, allowing flexible customization within a single SVG canvas.

Color and size legends

This example demonstrates two types of legend encodings for data visualization: a color legend mapping ordinal categories to hues, and a size legend scaling circles according to a square-root scale. The color legend displays fruit names with distinct colors, while the size legend shows numeric ticks with proportional circle radii. Built with D3 v5, the visualization uses `selectAll` and `.enter().append()` to construct SVG groups, circles, and text elements. Custom `colorLegend` and `sizeLegend` functions control the layout, with positioning handled via `attr('transform', ...)` and scales defined by `scaleOrdinal` and `scaleSqrt`.

Color and Size Legends

This example demonstrates two distinct legend types rendered side by side in SVG. A color legend uses `d3.scaleOrdinal` to map fruit categories—apple, lemon, lime, and orange—to distinct hues, with each entry displayed as a filled circle and label. A size legend uses `d3.scaleSqrt` to encode a numeric domain from 0 to 10 through varying circle radii, generating tick values via `sizeScale.ticks`. Both legends are constructed with reusable D3 functions that bind data to groups, updating circle and text elements on enter and merge.

Color and Size Legends

This example demonstrates two custom legend types rendered as SVG: a color legend mapping ordinal fruit categories to distinct hues, and a size legend using a square-root scale to encode numeric values through circle radii. The color legend uses `d3.scaleOrdinal` with domains for apple, lemon, lime, and orange, while the size legend employs `d3.scaleSqrt` with tick marks generated from the scale. Both legends are built procedurally using custom functions (`colorLegend` and `sizeLegend`) that append grouped circles and text elements, with spacing and offset parameters controlling layout. The visualization is constructed with D3 v5 and rendered entirely in SVG, with styling applied via CSS classes.

Color and Size Legends

This example demonstrates two custom legend components built with D3 v5 and rendered as SVG. A color legend uses `scaleOrdinal` to map fruit categories to distinct circle fills, while a size legend employs `scaleSqrt` with `ticks()` to encode numeric values as varying circle radii. Both legends bind data to grouped `<g>` elements, applying enter/merge/exit selections for dynamic updates. The code defines reusable functions `colorLegend` and `sizeLegend`, called via `.call()`, with text labels positioned using `textOffset`.

Color and Size Legends

This example demonstrates two reusable legend components rendered with SVG in D3 v5. The color legend uses `d3.scaleOrdinal` to map categorical fruit names to a custom color range, displaying each swatch with a fixed circle radius and text offset. The size legend uses `d3.scaleSqrt` to map numeric values from 0 to 10 to proportional circle radii, with tick marks generated via `sizeScale.ticks()`. Both legends are positioned within a single SVG and styled through shared CSS classes, highlighting how D3’s data joins and merge patterns update legend elements dynamically.
