What problem does it solve?

ECharts Visualization helps engineers design, debug, and optimize chart options so charts render correctly, remain responsive, and perform well under real data loads.

Core Features & Use Cases

• Option design: build minimal, maintainable option objects and prefer dataset + encode for multi-series mapping.
• Interactions & responsiveness: implement tooltip, legend, dataZoom, click handlers, resize behavior, and lifecycle cleanup.
• Performance tuning: apply progressive rendering, hide symbols for dense lines, use setOption with lazy updates, and dispose charts on unmount.
• Use Case: convert raw time-series data into a responsive Vue/React chart with correct axis formatting, centralized theme tokens, and verified memory safety.

Quick Start

Create a minimal responsive ECharts option for a multi-series line chart using dataset and encode, validate rendering on desktop and mobile, and confirm no duplicate instances after navigation.
