Getting Started Requirements
Requires JavaScript programming knowledge, no server deployment needed (frontend library), no API Key required.
Purpose
Suitable for scenarios requiring high-performance web graphics interaction, such as online design tools or data dashboards. Not suitable for zero-basis users or scenarios needing only static image display.
