Two New Chart Types: Sankey & Treemap
DataVizForge has expanded its chart library with two powerful visualization types: Sankey diagrams and treemaps.
Sankey Diagrams
Sankey diagrams visualize flows and their quantities between entities. The width of each flow line is proportional to the quantity it represents.
Use cases:
- Budget allocation and spending breakdowns
- User journey and conversion funnels
- Energy or resource flow analysis
- Supply chain and logistics mapping
Features:
- Drag-and-drop node positioning for optimal layout
- Custom color mapping per source or target node
- Interactive tooltips showing exact flow values
- Export to PNG, SVG, or WebP
Treemaps
Treemaps display hierarchical data as nested rectangles, where each rectangle's area is proportional to a specified value.
Use cases:
- Portfolio composition and asset allocation
- Market share visualization by category
- Disk usage and storage analysis
- Product category revenue breakdown
Features:
- Multiple tiling algorithms (squarified, slice-and-dice, striped)
- Color gradient mapping based on any numeric dimension
- Drill-down into nested hierarchies with click
- Responsive sizing for dashboard embeds
Getting Started
Upload your data via Excel or CSV, select "Sankey" or "Treemap" from the chart type dropdown, and map your columns to source, target, and value fields. Both charts are available to all registered users at datavizforge.com.
