Type Declaration

Name	Type	Default value	Description
ggplot2	Template	-	R's ggplot2 look: grey panel, white grid, ggplot's hue palette.
gridon	Template	-	Grid lines on both axes, e.g. 'simple_white+gridon'.
high-contrast	Template	highContrast	-
high-contrast-dark	Template	highContrastDark	-
holochart	Template	-	The default look (ADR-021), applied to every figure without layout.template: a dark, dense chart with a #0a0a0f background, 9 px Helvetica Neue text, tight margins, a horizontal legend above the plot area and the "neon plasma" sequential colorscale. The same object as core's holochartTemplate, which the runtime registers in every bundle.
holochart-dark	Template	holochartDark	Deprecated An alias of holochart (ADR-021).
neon	Template	-	The glow showcase: saturated neon hues on a near-black indigo background, a faint cyan grid, a magenta zero line, and a luminous title halo (title.font.shadow). Markers and bars get a thin white-hot rim and lines are 2.5 px, which reads as a glowing core. Approximation: the plan's 3D glow is a bloom post-processing pass (E8.12), which does not exist yet; in 2D the glow is approximated by the rims, the text halo and the palette's luminance against the dark background. When bloom lands, this template turns it on. Colorscales are interpolated in Oklab (colorscaleInterpolation), which keeps the neon ramps bright through their midpoints.
none	Template	-	The empty template: the library's schema defaults (Plotly's look), as with layout.template: null. The same object as core's noneTemplate, which every bundle registers.
plotly	Template	-	plotly.py's default template: blue-grey plot area, white grid, the Plotly colorway, Plasma.
plotly_dark	Template	-	plotly.py's dark template: near-black background, slate grid, light text.
plotly_white	Template	-	plotly on white, with light blue-grey grid lines.
plotly-classic	Template	plotlyClassic	-
presentation	Template	-	Larger text and thicker lines for slides (compose it: 'plotly_white+presentation'): 18 px base font, 3 px lines, 9 px markers, taller table rows.
seaborn	Template	-	Python seaborn's "darkgrid" look: lavender-grey panel, white grid, the deep palette.
simple_white	Template	-	Minimal white template: no grid, dark axis lines with outside ticks, D3 colors, Viridis.
xgridoff	Template	-	No vertical grid lines (compose it with another template).
ygridoff	Template	-	No horizontal grid lines (compose it with another template).
