cargo add chartlet

use chartlet::{render_json, RenderFormat, RenderOptions};

let spec = std::fs::read_to_string("examples/monthly-revenue.json")?;
let output = render_json(&spec, RenderFormat::Html, &RenderOptions::default())?;
for warning in &output.warnings {
    eprintln!("{} at {}: {}", warning.code, warning.path, warning.message);
}
std::fs::write("chart.html", output.content)?;

With RenderOptions { manifest: true, .. }, output.manifest holds the provenance of the render (Manifest::to_json writes the JSON of --manifest). chartlet::sha256 is the SHA-256 it hashes with.

An architecture model with views renders its default view, or the one in RenderOptions { view: Some("checkout".into()), .. }. ChartSpec::view resolves a view to a specification of its own, for text_alternative or render_png; ChartSpec::view_keys lists the keys. RenderOptions { all_views: true, .. } renders every view on one HTML page, and Manifest::views lists them. RenderOptions { perspective: Some("debt".into()), .. } shows a perspective in place of the one the model or the view selects; ChartSpec::with_perspective does the same to a specification, before view. inspect_json runs the inspections of an architecture model, flow chart or class diagram, leaving out the codes it is given (INSPECTIONS lists them all).

ChartSpec::tokens and theme restyle a chart; apply_theme(spec_json, theme_json) applies a theme file to a specification given as JSON text, and bundled_theme("dark") returns the text of a bundled one, see Customize the look.

With the png feature (cargo add chartlet --features png), render_png rasterizes the print or the social variant, see Social images and PNG.

render_with_metrics accepts your own TextMetrics implementation if your pages use a font whose widths differ noticeably from the built-in profile.

Every type and function is documented on docs.rs/chartlet.
