Plenum Atlas turns CSV or Excel files into interactive map dashboards. Drop your data, pick a region — your numbers appear on the map instantly. Click a country to filter tables and charts. 8 visualization types, 10 map styles, export to PowerPoint, PDF, Word, or standalone HTML. 100% local, GDPR-friendly, one-time purchase. Built for analysts and consultants who want map dashboards without Tableau or GIS.
