Nationwide Lottery Heat Map Desktop

I need to turn the daily lottery draws for all 50 states into a colour-coded Heat Map that runs as a stand-alone Windows desktop application. The program must read 3-, 4- and 5-digit results straight from CSV or Excel sheets that I will drop into a folder each day, then refresh the visualisation automatically so the map always reflects the newest numbers.

Key points I care about • A responsive, zoomable U.S. map that shades each state according to configurable metrics (frequency, last hit, highest payout, etc.). • Smooth ingestion of fresh CSV/Excel files without manual re-formatting; one click or timed auto-update is ideal. • Unlimited daily updates—no hard-coded data limits. • Clear filtering so I can isolate specific number lengths, states or date ranges on demand. • Clean Windows install with no external licences I must purchase. You are free to build in WPF, WinForms, Electron, Python + PyInstaller, or another stack you recommend, provided the final exe runs on current Windows 10/11 machines.

Deliverables

• Compiled Windows executable
• Fully commented source code
• README or short video showing how to load new files and adjust settings
• Sample input files so I can test immediately

Acceptance criteria: loading a new CSV of today’s draws and seeing the map refresh without errors in under 30 seconds.

If you have experience with mapping libraries such as Leaflet, Plotly, D3, ArcGIS Runtime, or similar—and can demonstrate a past data-visualisation project—let me know how quickly you could deliver a first working prototype.
