Browse theme river chart layouts
Theme river chart templates—sometimes called streamgraphs—show how multiple categories contribute to a total across a timeline. Gallery layouts include smooth stacking, color bands per theme, and time axes suited to media topics, product mix, or seasonal demand shifts.
Pick a template when you want flowing ribbons instead of rigid stacked areas. Click a preview to load multi-series samples in the editor, then map your dates and category weights from a spreadsheet or paste table.
Copy here emphasizes template discovery and layout previews, leaving creation-focused keywords for a future theme river maker page. Use this gallery to compare stream styles before customizing data.
Stream smoothing and baseline symmetry differ between cards. Pick a template whose silhouette matches whether you want to emphasize individual topic peaks or the overall mix across the timeline.

Topic trend stream template
Start from a layout with several colored ribbons when you need to show how themes rise and fall across months or weeks.
Product mix over time preview
Use templates where each band is a SKU family or region contributing to total volume along a date axis.
Symmetric versus baseline stream styles
Gallery options differ in how streams center on the axis—pick one that matches whether you highlight peaks or overall composition.

Frequently asked questions
- What data format do theme river templates use?
- Samples pair a time field with multiple category columns or long-format rows. Edit in the data panel or import CSV after opening a template.
- How is a theme river template different from a stacked area chart?
- Theme river layouts emphasize flowing, centered streams. Stacked area templates use rigid layers—pick the gallery family that fits your narrative.
- Can I reorder ribbon colors in the editor?
- Yes. After loading a template you can change series order and colors without rebuilding the time axis.
- Why list theme river templates separately from a maker page?
- This URL targets browsing ready-made stream layouts. Maker content can own generator queries elsewhere.
- Can theme river templates stack many categories?
- Yes, but readability drops as bands multiply. Start with a gallery layout close to your category count and merge minor streams in the data panel if ribbons become too thin.
