v0.36.0

Added

• Repelled labels keep clear of straight lines: RepelParams::avoid_ablines and the avoid_abline(slope, intercept) builder on GeomTextRepel / GeomLabelRepel (DataZooDE/anofox-visualization#753).

Changed (breaking)

• RepelParams has a new public field (avoid_ablines).

v0.35.3

Added

• format::format_timestamp(secs, fmt, locale): the datetime scales' strftime subset, with a locale's month and weekday names, for hosts that format a date the way an axis does (anofox-visualization#751).

v0.35.2

Fixed

• An inside legend no longer runs off a right-hand panel edge
  (LegendPosition::Inside, legend_inside_auto). Its width was estimated
  as six characters per label and ignored the title, so at a right corner a
  longer label or title was drawn past the panel (and cut off by the
  canvas). The estimate now measures the widest label and the title as
  drawn.

v0.35.1

Added

• npm package @sipemu/ggplot-rs (#382): the wasm build is published
  to npm from the same GitHub release as the crate, at the same version
  (.github/workflows/npm.yml, with provenance; js/check-version.mjs
  checks that the versions match in CI and on release).
  • render(spec) / renderWithWarnings(spec) take a layered spec
    ({ data, aes, layers: [{ geom, aes, data, params, stat, position }], scales, facet, coord, labels, theme, legend, width, height }) as a JS
    object or as JSON text. It covers 53 geoms, including waterfall, sankey,
    chord, treemap, sunburst and candlestick; facet wrap/grid with free
    scales; coord flip/polar/fixed/radar/zoom; theme presets or a
    ThemeConfig overlay; and the legend position, including inside.
  • The shipped .d.ts has a typed PlotSpec.
  • Errors are Error objects naming the bad field. An unknown column
    lists the available ones; unknown geoms, aesthetics and spec fields are
    rejected.
  • The package is SVG-only, about 0.59 MB of gzipped .wasm. CI runs
    vitest against the built package, a typecheck of the shipped .d.ts,
    and wasm-bindgen tests.

Fixed

• A tagged grid element keeps clear of its tag (GridElement with
  tag_levels). The tag sits in a band twice the title size at the cell's
  top (or bottom, with a bottom tag position) and the element is drawn in the
  rest of the cell, as a plot cell's margin already leaves room for its own.
  Previously a table or note drawn from the cell's top left sat under the
  tag.
• Title and subtitle no longer overlap (#384). Previously the subtitle
  was centred 2px above the panel, so its lower half sat inside the panel,
  and it overlapped the title at the default sizes. Both now stack inside
  the bands the layout reserves. This applies to the single-panel and
  faceted paths, and the subtitle is now also lifted above a top x-axis.
  A title with no subtitle stays where it was.

v0.35.0

Added

• GridElement — non-plot PlotGrid cells (patchwork's
  wrap_elements, #378): GridElement::fixed(svg, w, h) scales a fragment
  drawn in its own w × h box into the cell keeping its aspect;
  GridElement::fill(|w, h| svg) renders at the cell's real size. The cell
  is a nested <svg … data-cell="i">, takes part in widths/heights and
  tag_levels, and is skipped by axis_collect / collect_legends; the
  | / / operators accept it. Markup is inserted verbatim.

Fixed

• Inside legends (LegendPosition::Inside, legend_inside_auto) are inset
  by legend_margin from the panel edges, and the title — drawn centred on
  the legend origin — no longer sticks out above the box (it was clipped in
  a top corner); a colourbar's bottom label overhang is counted too (#377).

Changed

• Breaking: GridCell has a new Element variant (exhaustive matches
  need an arm).
• Inside legends with a non-zero legend_margin sit that margin further
  in from the panel edge.

v0.34.0

Added

Highcharts chart-type parity (#296–#326), each with a geom_* shortcut and a
configurable geom_*_with:

• Business / KPI: geom_waterfall (#296), geom_pareto (sorted bars +
  cumulative-% line on a SecAxis::percent_of_max axis, #297),
  geom_funnel / geom_pyramid (#303), geom_bullet (#307),
  geom_lollipop / geom_dumbbell (#306), geom_variwide /
  geom_marimekko (#314).
• Flows & networks: geom_sankey (#298), geom_chord (#299),
  geom_arcdiagram (#300), force-directed geom_network (#310),
  geom_flow origin–destination flow maps (feature sf, #324).
• Hierarchies: squarified geom_treemap (#301), geom_sunburst /
  geom_icicle (#302), geom_packed_bubble (#309), geom_tree / org
  charts / geom_dendrogram (#311).
• Sets & units: geom_waffle / geom_parliament (#308), area-
  proportional geom_venn (#312), geom_wordcloud (#313),
  geom_variable_pie (#319).
• Time: streamgraphs via StackOffset (silhouette, wiggle) +
  geom_stream (#304); spline Interpolate (monotone cubic, Catmull-Rom)
  on line / area / ribbon (#305); geom_timeline (#315); geom_xrange
  Gantt charts (#316); geom_flags event flags (#323).
• Finance: hollow candles, geom_hlc, geom_heikin_ashi (#320);
  geom_renko / geom_point_figure (#321); StatIndicator — SMA, EMA,
  WMA, Bollinger, MACD, RSI, ATR, VWAP, stochastic, ZigZag (#322).
• Maps & weather: geom_tilemap tile-grid cartograms (+
  us_state_grid, #317), geom_windbarb (#318).
• Tiled basemaps (new feature tiles, #325):
  annotation_map_tile(TileSource::xyz(..), fetcher) draws XYZ raster tiles
  (OpenStreetMap and friends) under Web-Mercator geom_sf layers, with the
  source's attribution. No networking in the crate: tiles come from a
  caller-supplied TileFetcher (any Fn(z, x, y) -> Option<Vec<u8>>) and
  are cached per layer. New DrawBackend::draw_image (default: no-op),
  implemented by the native SVG, canvas and plotters backends.
• GGPlot::legend_inside_auto() / legend_inside_auto_with(corners, fallback) (#332): the legend goes inside the panel in the first corner
  where its real box overlaps no drawn mark, else outside on the side
  (Top/Right) that leaves the data area larger. The choice is the root
  data-legend-at attribute.
• GGPlot::facet_levels(&[..]) (#329): explicit facet_wrap panel
  order; levels without data keep an empty panel (ggplot2's drop = FALSE).
• PlotGrid::legend_bottom_when_narrow(share) (#363): a grid's
  collected legend column moves below the grid on narrow renders.
• Examples: inventory_twin (quantile fan + PlotGrid alarm strip, #124)
  and map_tiles; README gallery and chart-family overview (#326).

Fixed

• ScaleDateTime::with_date_labels is honoured on automatic month and year
  breaks (#352).
• position_jitter / geom_jitter / position_jitterdodge now jitter on a
  discrete x axis (points used to stay on the category's centre line).
• A Bottom legend under an axis-less theme (theme_void) stays on the
  canvas instead of being placed at its edge with zero height (#341).
• The caption is drawn inside its reserved area, below a Bottom legend
  (#286).
• The y axis title keeps a gap to short tick labels; a faceted grid draws
  one x and one y axis title instead of one per panel (#348).
• Chart-type shortcuts (geom_waterfall, geom_funnel, geom_waffle, …)
  honour theme ink/paper and primary_color (#362).

Changed

• Breaking for struct literals without ..Default::default(): new
  fields interpolate on GeomLine / GeomArea / GeomRibbon, style /
  open_tick on the candlestick geoms, offset on PositionStack,
  percent_of_max on SecAxis, and levels on Facet::Wrap.

v0.33.0

Small-multiple maps (#293): fixed-aspect facet_wrap under coord_sf, per-panel clip, data-viewport/data-panels root attributes, GeomAttribution::figure, ScaleFillBinned::show_counts, GeomNorthArrow.

v0.32.0

GeomPoint::visibility / hidden_targets (#290): hide markers on dense series while keeping them as hover/click targets. Breaking: new pub fields on GeomPoint.

v0.31.8

Opt-in GGPlot::legend_bottom_when_narrow(share): a Right legend moves below a narrow panel (#287). See CHANGELOG.md.

v0.31.7

A subtitle without a title no longer overlaps a Top legend (#281). See CHANGELOG.md.
