Flow Map for Power BI

Flow Map for Power BI brings your movement data to life. Whether you're tracking trade routes, customer journeys, migration patterns, or logistics flows, Flow Map turns raw origin-destination data into stunning, interactive geographic visualizations — with no API keys, no subscriptions, and no limits. How it works Simply connect your data with Origin and Destination location names (or coordinates), add a flow value, and Flow Map instantly renders beautiful curved lines between your locations on an interactive map. The visual automatically handles geocoding — just use plain text location names and the map figures out the rest. Key Features Flow visualization — Straight, arc, or bundled flow lines between any two geographic points Automatic geocoding — Type location names in plain text; no coordinates required Multiple map styles — Road, Grayscale, Dark, Light, or hidden background Bubble charts — Display aggregated totals at origin and/or destination points Colour coding — Color flows by category or apply a single custom colour Line width scaling — Flow line width scales proportionally to your values Rich tooltips — Hover over flows and bubbles to see detailed data Legend support — Automatic legend generation for colour-coded flows 18 map languages — Display map labels in your preferred language High performance — Handles 50+ simultaneous flows smoothly Data Fields Field Required Description Origin ✅ Yes Starting location name or ID Destination ✅ Yes Ending location name or ID Values Recommended Flow quantity (controls line width) Color Optional Category for colour-coding flows Origin Lat / Lon Optional Skip geocoding with exact coordinates Destination Lat / Lon Optional Skip geocoding with exact coordinates Tooltips Optional Extra fields shown on hover Labels Optional Custom labels shown on the map Completely Free Flow Map is 100% free to use with no hidden costs. It is powered by open-source technology (MapLibre GL JS, OpenStreetMap, and the Photon geocoding API) with no usage limits or API keys required.
