: Features a collection of minimalist HMI and Human-Machine Interface icons .
| Scenario | Recommended approach | |----------|----------------------| | (e.g., for Raspberry Pi) | Qt + OpenSCADA widgets + Material SVG icons (MIT) | | Commercial HMI device (no license fee for graphics) | Use MIT/CC0 icon sets only; code custom controls using basic shapes (no GPL assets) | | Web‑based HMI | Apache ECharts for gauges + FontAwesome + custom SVG mimic (Inkscape) | | Rapid prototype | HMI Project (GitHub) or ModernUI for WinForms (free) | | No time for DIY | Purchase affordable commercial library (e.g., Industrial Graphics from CodeProject, ~$50) – outside “free” scope, but practical | free hmi graphics library
