Flowcharts are essential tools for visualizing processes, algorithms, and system architectures. Here are best practices for creating effective, enterprise-grade flow diagrams with Elehua AI's interactive canvas.

Start With the Right Node Types

Elehua AI's flow generator supports 7 node types — each with a distinct visual shape and semantic meaning:

• Start / End (oval) — Entry and exit points of the flow

• Process (rectangle) — Standard operations and actions

• Decision (diamond) — Branching logic with yes/no or multiple paths

• Input/Output (parallelogram) — Data entering or leaving the process

• Database (cylinder) — Data storage operations

• Subprocess (double-bordered rectangle) — Collapsed sub-processes with their own flows

• Annotation — Supporting notes and clarifications

Structure Principles for Clear Diagrams

1. Flow top-to-bottom or left-to-right — Readers scan in reading order, so respect that convention

2. One entry point, one exit point — Keeps the diagram focused and easy to follow

3. Limit decision branches to 2-3 options — More than 3 branches per decision node creates confusion

4. Label every arrow — Don't assume the path is self-explanatory

5. Keep labels short — 3-7 words per node label is the target

6. Group related nodes — Use background containers to show subsystems

Export & Integration Tips

Once your diagram looks right, export it as PNG for presentations, SVG for technical documentation (scales infinitely without blur), or embed it in Notion, Confluence, or any wiki that accepts images.

Use auto-layout (press the layout button) before exporting — it spaces nodes evenly and reduces crossing arrows automatically.
