Venn Diagram 3D

Signature

sp.venn3d(title, labels=None, values=None, *, variant="basic", orientation3d="iso", scene="default", theme="none", zone=None, max_points=None, bg_color="#1a1a2e", width=560, height=420, x_label="", y_label="", z_label="", **kwargs) -> Chart

Aliases: sp.build_venn3d_chart(), sp.venn_3d(), sp.venn3d_chart(), sp.euler3d(), sp.set_diagram3d().

Description

sp.venn3d() is the 3D twin of sp.venn(): all 5 venn variants share the same 3D form, selected with the same variant keyword and fed with the same set sizes. A literal overlapping-circle shape has no honest cuboid form, so each set instead gets its own column, laid out on the same 1/2/3/N-set topology as the 2D chart (two sets side by side, three in a loose triangle); euler additionally sizes each column by its own value.

Variants

VariantAliasesUses3D form
basicdefault, classiclabels, valuesOne uniform-height column per set.
eulerproportional, arealabels, valuesOne column per set, height scaling with its own value.
filledsolid, opaquelabels, valuesThe same uniform columns as basic, from the 2D chart’s solid-fill styling.
minimaloutline, thinlabels, valuesThe same uniform columns as basic, from the 2D chart’s outline-only styling.
exclusiveunique, distinctlabels, valuesThe same uniform columns, toned down to a dimmer read.

Data

labels names each set and the first N entries of values (N = number of sets) give each set’s own total.

3D planes

The viewpoint is independent from the variant: orientation3d picks the initial camera plane and applies to every variant; the view always stays draggable.

orientation3d="iso" — Isometric three-quarter view (default).
orientation3d="horizontal" — Side-on view, almost at floor level.
orientation3d="vertical" — Top-down view from above.
orientation3d="front" — Front elevation, nearly flat.

3D scenes

scene swaps the environment the columns are drawn in and applies to every variant and every plane.

scene="default" — Each series keeps its own categorical palette color, rendered as shaded 3D bars on a flat grid.
scene="terrain" — The data is resampled onto a dense grid and rendered as hundreds of thin colormap-colored columns, forming a continuous mountain-of-bars terrain.
scene="tower" — The data is resampled onto a dense field of round skyscraper-like towers instead of boxes, for a city-skyline reading of magnitude.
scene="radial" — The data is resampled onto a dense polar grid of rings and wedges radiating from the center, like a 3D radar/sonar sweep of the value field.
scene="podium" — The data is resampled onto a dense grid and quantized into stepped terrace levels, like a rice-terrace contour map, to read value bands at a glance.

Themes

theme restyles the whole canvas (colour grade and glow) and applies to every variant, scene and plane.

theme="deluxe"
theme="prism"
theme="aurora"
theme="inferno"
theme="frost"
theme="glow"
theme="glass"
theme="neon"
theme="cosmic"

Auto-scaling zone

The 3D zone (floor, walls, axes and camera) scales to the elements: its length, width and height follow the extents of the drawn blocks, a minimum floor depth keeps single rows readable, wide scenes are drawn flatter and the camera frames the whole box. The axis ticks read the real data range. Pass zone=[x, y, z] to force the proportions of the box instead; the longest side is normalised to 1.

Parameters

Returns

Chart object with an .html property and a .show() method.
