Streamgraph
A streamgraph is a stacked area chart with a flowing, centered baseline, so the total appears as a smooth shape that expands and contracts over time. It de-emphasizes a fixed zero baseline in favor of relative composition, making it well suited to topic share over time, music-gen

When to use this template
This visualization excels at revealing how the composition of a whole changes over time, highlighting shifts in the relative proportions and dominance of its constituent categories. An analyst would reach for it to understand the evolution of a mix, identify emerging or declining trends within components, and observe the overall expansion or contraction of the total. It's ideal for understanding dynamic proportional relationships rather than precise comparisons against a fixed baseline.
- Time-series data with a continuous temporal dimension.
- Multiple categorical series contributing to an aggregate total.
- When relative proportions and shifts in dominance are the primary insight.
- Datasets where the absolute value of individual categories is less critical than their share.
- Aggregated data representing a whole, broken down by type.
- Moderate number of categories to ensure readability without clutter.
