@datafe-open/markdown-chart-markdown-it

A markdown-it fence plugin that emits safe generated placeholders. Chart source is returned through the render environment rather than copied into HTML.

Pass the live renderer registry to the plugin so explicitly registered aliases and dynamic renderer languages are routed without adapter-specific language configuration. A renderer identifier alone is not treated as a fence language:

const md = new MarkdownIt({ html: false })
  .use(markdownChartPlugin, { registry });

The canonical markdown-chart fence is always recognized. Advanced hosts may supply an isChartLanguage predicate instead of, or in addition to, a registry.

Streaming hosts can create the render environment with createMarkdownChartEnvironment({ streaming: true }). Each collected block then reports complete; closed blocks can mount immediately while an unterminated tail block remains pending.
