## Instructions

1. Set size and theme in Basic Config;

2. Enter chart options as pure JSON config (no code execution, no function strings);

3. Use Variable Assignment to define variables as pure JSON; reference them in Options via ${publicVar.x} or ${publicVar.x * 2};

4. Click Generate Chart to preview;

5. Use Export Options to save chart or config;

6. Use Chart Templates for ready-to-run examples (demo purpose, logic accuracy not guaranteed);

Tip:
Refer to examples to generate valid JSON.，The string is parsed from textarea by JSON.parse and passed to ECharts option. Two strict rules: 1. No // comments or non-JSON syntax. Functions must be strings wrapped in double quotes. 2. Proper indentation is required.
