📊 twinBASIC Monthly Challenge #3 - March

Create a Data Viewer

Build an application that reads data from a file or the system and presents it in a useful or interesting visual way.

Your program should take raw or structured data and turn it into something that people can explore, analyse, or understand more easily.

This could be a viewer, explorer, dashboard, inspector, or visualisation tool.

Examples include (but are not limited to):

  • Access MDB / ACCDB file viewer
  • JSON or XML explorer
  • CSV / spreadsheet viewer
  • SQLite database browser
  • Log file viewer
  • Windows Event Log viewer
  • Windows Registry explorer
  • Image metadata (EXIF) viewer
  • Folder size visualizer
  • System metrics dashboard
  • Network data viewer

Creativity is encouraged - unusual data sources or interesting visualisations are welcome.
