Module element 

Structs

Dimensions

ElementData

Data attached to interactive elements for tooltips.

TextStyle

Resolved typography for a single ChartElement::Text literal. All fields are already prepared as Option<String> — plug them directly into the Text enum variant.

ViewBox

Enums

ChartElement

The output of any ChartRenderer. Framework adapters walk this tree and produce framework-specific DOM/view output.

TextAnchor

TextRole

Role of a text element, used to select the right bundle of typography fields from the active Theme.

Transform

Constants

LEGACY_FONT_WEIGHT

Legacy font-weight for all chrome text. None because no current emission site sets font-weight at all — the attribute is absent from every pre-Phase-4 baseline SVG.

LEGACY_LABEL_FONT_SIZE

Legacy hardcoded font-size string for axis labels and tick labels.

LEGACY_LEGEND_FONT_SIZE

Legacy hardcoded font-size string for legend labels. Note this differs from LEGACY_LABEL_FONT_SIZE — the legend has historically used a slightly smaller size (11px) while all other chrome uses 12px.

Functions

count_elements

Count elements in the tree matching a predicate.

emit_dot_halo_if_enabled

Emit a halo element to render BEFORE a dot marker, or None when theme.dot_halo_color is None. Uses theme.dot_halo_width as the stroke width. The halo radius always matches the dot’s own radius so the ring hugs the dot — bubble charts pass the per-point radius here, not a static theme default.
