v0.6.16

Compare Source

Released August 6, 2024.

The new waffle mark 🧇 displays a quantity (or quantitative extent) for a given category; unlike a bar, a waffle is subdivided into cells that allow easier counting, making waffles useful for reading and comparing exact quantities. Plot’s waffle mark is highly configurable: it supports stacking, positive and negative values, rounded corners, partial cells for fractional counts, automatic row or column size determination (with optional override), and more!

Plot.plot({
  fx: {interval: 10},
  color: {legend: true},
  marks: [Plot.waffleY(olympians, Plot.groupZ({y: "count"}, {fill: "sex", sort: "sex", fx: "weight", unit: 10}))]
})

All marks now support GeoJSON data and GeoJSON property shorthand, making it easier to work with GeoJSON. For example, below the data counties is a GeoJSON FeatureCollection, and unemployment refers to a property on each feature; the fill option is thus shorthand for (d) => d.properties.unemployment. The geo mark now also supports the tip option (via an implicit centroid transform), making it easier to use Plot’s interactive tooltips.

Plot.plot({
  projection: "albers-usa",
  color: {
    type: "quantile",
    n: 9,
    scheme: "blues",
    label: "Unemployment (%)",
    legend: true
  },
  marks: [
    Plot.geo(counties, {
      fill: "unemployment",
      title: (d) => `${d.properties.name} ${d.properties.unemployment}%`,
      tip: true
    })
  ]
})

All marks now also support column name channel shorthand when using Apache Arrow tables as data, and we’ve added detection of Arrow date-type columns. (Arrow represents temporal data using BigInt rather than Date.)

Plot.dot(gistemp, {x: "Date", y: "Anomaly"}).plot() // gistemp is an Arrow Table!

The rect-like marks (rect, bar, cell, and frame) now support individual rounding options for each side (rx1, ry1, etc.) and corner (rx1y1, rx2y1, etc.). This allows you to round just the top side of rects. You can even use a negative corner radius on the bottom side for seamless stacking, as in the histogram of Olympic athletes below.

Plot.plot({
  color: {legend: true},
  marks: [
    Plot.rectY(olympians, Plot.binX({y: "count"}, {x: "weight", fill: "sex", ry2: 4, ry1: -4, clip: "frame"})),
    Plot.ruleY([0])
  ]
})

Plot now respects the projection domain when determining the default plot height. Previously, the map below would use a default square aspect ratio for the conic-conformal projection regardless of the specified domain, but now the map is perfectly sized to fit North Carolina. (Plot also now chooses a smarter default plot height when the ordinal y scale domain is empty.)

Plot.plot({
  projection: {.
    type: "conic-conformal",
    parallels: [34 + 20 / 60, 36 + 10 / 60],
    rotate: [79, 0],
    domain: state
  },
  marks: [
    Plot.geo(counties, {strokeOpacity: 0.2}),
    Plot.geo(state)
  ]
})

The marker options now render as intended on marks with varying aesthetics, such as the spiraling arrows of varying thickness and color below.

Plot.plot({
  inset: 40,
  axis: null,
  marks: [
    Plot.line(d3.range(400), {
      x: (i) => i * Math.sin(i / 100 + ((i % 5) * 2 * Math.PI) / 5),
      y: (i) => i * Math.cos(i / 100 + ((i % 5) * 2 * Math.PI) / 5),
      z: (i) => i % 5,
      stroke: (i) => -i,
      strokeWidth: (i) => i ** 1.1 / 100,
      markerEnd: "arrow"
    })
  ]
})

This release includes a few more new features, bug fixes, and improvements:

The new className mark option specifies an optional class attribute for rendered marks, allowing styling of marks via external stylesheets or easier selection via JavaScript; thanks, @​RLesser! Plot now reuses clipPath elements, when possible, when the clip mark option is set to frame or projection.

The difference mark now supports a horizontal orientation via differenceX, and the shift transform now likewise supports shiftY. The Voronoi mark is now compatible with the pointer transform: only the pointed Voronoi cell is rendered; the Voronoi mark now also renders as intended with non-exclusive facets (as when using the exclude facet mode). The tip mark no longer displays channels containing literal color values by default.

v0.6.15

Released June 11, 2024.

v0.6.14

Compare Source

Released March 12, 2024.

Changes the default categorical color scheme to Observable10.

The group transform now preserves the input order of groups by default, making it easier to sort groups by using the sort option. The group and bin transforms now support the z reducer.

Improves the accessibility of axes by hidding tick marks and grid lines from the accessibility tree.

Upgrades D3 to 7.9.0.
