Elm code blocks compile and execute in real-time with results embedded directly in the markdown, enabling immediate feedback and iterative design as shown in the hello world and chart examples.

Symbols defined in one code block can be referenced in others or in text using triple-hat notation (^^^), allowing seamless integration of code and narrative, as demonstrated in the parameterized references example.

Supports interactive charts and user input controls via Vega-Lite/Vega specifications, with the 'interactive' attribute making visualizations live, as highlighted in the interaction GIF.

Branching narratives and YAML-based schemas provide scaffolding for organizing and validating content around visualizations, facilitating reproducible research and design exploration.
