Chart types
Panels supports bar, line, area, scatter, pie, heatmap, gantt, and sankey charts. Each chart type has configurable axes, aggregations, colors, and tooltips.
Tables
Table blocks display tabular data with sorting, pagination, column resizing, and conditional formatting.
Maps
Map blocks render geographic data with configurable layers, zoom levels, and point/polygon styling.
Metrics
Metric blocks display a single KPI value with optional trend indicator, comparison period, and formatting.
Cross-filtering
In dashboards, clicking a chart element filters all other visualizations automatically. No wiring required.
