Plenum Atlas

Plenum Atlas converts CSV or Excel spreadsheets into interactive map dashboards on Mac and Windows without requiring code or server connections. Users drag a spreadsheet onto the application, which automatically detects columns such as country names, ISO codes, coordinates, and numeric values, allowing multiple datasets to be layered on a single map. The tool offers ten built‑in map styles and eight visualization layers—including choropleth, points, bubbles, heatmaps, text labels, connection lines, and hub‑and‑spoke—supporting both provided shapefiles and user‑uploaded GeoJSON or shapefiles.

The interface provides draggable, resizable dashboard windows that can display data tables, bar, line, and pie charts, as well as KPI values. These windows stay synchronized with the map in real time, so interactions like clicking or hovering over a region instantly filter tables and update charts. The software is positioned for users who need to explore geographic data quickly and visually, such as analysts, planners, or anyone working with location‑based spreadsheets.
