About the demo environment
- You can start drawing right in your browser, with nothing to install.
- Pen pressure is applied on devices that send pressure (such as a stylus) — with a mouse, lines are drawn at an even width.
- Sample data (names, records) is in Korean — the interface text appears in the language you chose.
