Visualizations
Geo Map charts
Plot networks, routes, markers, region fills, and heatmaps on an India or world map from query columns.
Updated August 15, 2026
Geo Map (chart type geo-route) uses Apache ECharts map overlays. India (states) is the default basemap. Nodes, edges, and markers come from your query — or from a built-in India sample when the result is empty.
Choose a map style
Open Visualization Setting → Map type.
| Style | What it shows | Columns to map |
|---|---|---|
| Network (geo graph) | Cities as nodes, connections as arrows | Place name, longitude, latitude, edge source, edge target |
| Animated routes | Curved paths with a moving trail | Same as Network |
| Markers | One point per row | Place name, longitude, latitude |
| Ripple markers | Pulsing points | Same as Markers |
| Region fill | States or countries colored by a metric | Region name, value |
| Density heatmap | Warm spots from coordinates + weight | Longitude, latitude, value |
| SVG map | Interactive SVG basemap (ECharts geo-svg-map) | Region name matching SVG name="..." attributes, optional value |
Guidance under the style dropdown updates as you switch.
Basemap
Map → Basemap defaults to India (states). Also available:
- India (country outline) — one polygon behind city markers
- World — country polygons
- Sicily (SVG) — official ECharts SVG topographic map (used by SVG map)
- Custom GeoJSON / SVG URL — any public FeatureCollection or SVG file
Pan and zoom are on by default. Region labels can be turned on for choropleths. SVG map supports single or multiple region selection, matching named paths in the SVG.
Pan and zoom are on by default. Region labels can be turned on for choropleths.
Dynamic nodes, edges, and markers
Point Data fields at your columns. Typical names are detected automatically (name, lng/lon, lat, source/from, target/to, region/state, value).
- Changing the query remaps points and links on the next render.
- Marker size scales a numeric column between the min and max marker sizes.
- India sample if empty (on by default) shows major Indian cities so you can preview styles before the query returns coordinates.
Region fill names
For India choropleths, region labels should match the map file. The default India states file uses names such as Maharashtra, Karnataka, Tamil Nadu, Delhi, West Bengal, Orissa (not Odisha), and Uttaranchal (not Uttarakhand). Common aliases are remapped automatically.
Appearance
Under Markers and edges and Appearance, each color uses a hex field and a native color picker (same control as scatter, heatmap, and table charts). Set land, border, hover land, marker, route, and choropleth/heatmap range colors independently.
