TLDR
This article explores how ECharts implements morphing transitions between different shapes. We'll examine the core implementation in the source code, breaking down the process into key steps including path conversion, structure alignment, and optimal rotation calculation. Through this analysis, we'll understand how ECharts achieves smooth shape transformations while maintaining visual continuity.

This article explores how to extend ECharts' global roaming functionality. While ECharts provides roaming through dataZoom for Cartesian charts, relationship-type charts lack full global roaming support. We'll examine ECharts' current single-series roaming implementation and develop a solution to enable global roaming across all chart types.
TLDR
In the past two years, my work has involved building chart components based on ECharts. This experience has given me a fundamental understanding of visualization component libraries. This article primarily introduces ECharts from the perspectives of timeline, feature and architecture.
