Crate cjc_vizor 

Vizor — grammar-of-graphics data visualization library for CJC.

Vizor is the first CJC library, validating the library architecture. It provides a declarative, grammar-of-graphics-style API for creating plots with deterministic rendering to SVG and BMP (and optionally PNG).

Architecture

PlotSpec → Layout → Scene → SVG / BMP / PNG
           (coord    (flat     (serializer)
            mapping)  primitives)

Usage from CJC

import vizor

let p = vizor_plot([1.0, 2.0, 3.0], [4.0, 5.0, 6.0])
    .geom_point()
    .title("My Plot")
    .xlab("X").ylab("Y")

p.save("plot.svg")

Modules

annotation

Semantic annotation types for data visualization.

bmp

BMP raster writer — uncompressed BMP format.

color

Color types, hex parsing, and default categorical palette.

dispatch

Vizor dispatch — maps CJC language calls to the concrete Vizor API.

docs

Builtin documentation metadata for IDE/LSP integration.

facet

Faceting — multi-panel grid layouts split by a grouping variable.

layout

Layout engine — coordinate mapping, tick generation, axis computation.

legend

Legend rendering — generates legend entries for multi-layer and categorical plots.

png_export

PNG export — behind the png feature flag.

raster

Shared rasterization: scene → pixel buffer.

render

Render pipeline — converts a PlotSpec into a Scene.

scene

Scene graph — flat list of positioned, styled primitives.

spec

Plot specification types — the declarative description of a plot.

stats

Statistical computations for Vizor plot types.

svg

SVG serializer — converts a Scene to SVG string.

text

Fixed-width text measurement policy.

theme

Theme definitions — margins, colors, font sizes, spacing.

Structs

VizorLibrary

CjcLibrary implementation for Vizor.
