Generate hierarchical radio frequency charts for your Arma 3 MILSIM unit from a JSON file.

• Input a nested JSON structure representing nets, squads, and fireteams
• Automatically generates a hierarchical chart image (PNG, SVG, PDF)
• Color-coded squads and their fireteams for easy visualization
• Lightweight CLI tool with no external dependencies except Graphviz
• Ready for future extension to web app or other input formats

Make sure the Graphviz system binaries are installed and available on your system PATH.

• Windows: Download and install from https://graphviz.org/download/
  Check "Add Graphviz to system PATH" during installation.

• macOS:

  brew install graphviz

• Ubuntu/Debian:

  sudo apt install graphviz

pip install radiochart

radiochart --input net_structure.json --output chart.png

{
  "Company Net (CH 1)": {
    "Platoon Net (CH 2)": {
      "Alpha Squad (CH 3)": {
        "Alpha Squad Fireteam 1 (CH 31)": {},
        "Alpha Squad Fireteam 2 (CH 32)": {}
      },
      "Bravo Squad (CH 4)": {
        "Bravo Squad Fireteam 1 (CH 41)": {},
        "Bravo Squad Fireteam 2 (CH 42)": {}
      },
      "Charlie Squad (CH 5)": {
        "Charlie Squad Fireteam 1 (CH 51)": {},
        "Charlie Squad Fireteam 2 (CH 52)": {}
      },
      "Whiskey Squad (CH 6)": {
        "Whiskey Squad Fireteam 1 (CH 61)": {},
        "Whiskey Squad Fireteam 2 (CH 62)": {}
      }
    },
    "Enablers (CH 7)": {},
    "Aviation (CH 8)": {},
    "Tac Air (CH 9)": {},
    "Medevac (CH 10)": {}
  }
}

This will generate a hierarchical chart image showing the nets, squads, and fireteams, with color-coded squads and their fireteams for clarity.
