Streamgraph
Visualize how multiple categories evolve over time as flowing, stacked layers centered around a baseline. Streamgraphs emphasize the organic shape of data and make it easy to spot which categories are growing or shrinking relative to others.
Examples
When to Use
- Showing how category proportions change over time
- Music genre popularity, traffic sources, or topic trends over months/years
- Emphasizing the aesthetic, flowing shape of temporal data
- Comparing relative growth across multiple series simultaneously

Tips & Best Practices
- Use smooth curves for organic, flowing aesthetics -- disable for more precise readings
- Keep the number of stream layers under 8 for clarity
- Streamgraphs emphasize relative proportions over time -- use area charts if absolute values matter more
