Sources

The Sources family contains nodes capable of rendering graphics directly on-screen without requiring any input. These include fundamental shapes such as Circle and Line, as well as more visually and functionally complex nodes like Grid, or self‑animating pattern generators such as Signal.

All Source nodes output a value of the datatype Figure which contains coordinates, rotation and other properties required for renderable elements.

Source nodes form the foundation of every visualization in Nodalin.

Keep in mind that if a graph does not include at least one Source node, the Render View remains hidden.

Support for polygons, spirals, and SVG parsing for complex shapes is on the roadmap!
