Description

每个项目在一个时间点的活跃度是以一个三维坐标（提交数增量、拉取请求数增量、贡献者数增量）确定的，因此可以用 SVG 结合 D3.JS 来绘制一个根据时间变化的动画图。

也应该可以支持多个项目的该指标的同时展示。

于此，我希望最终是一个Web 界面，可以勾选或输入（一个或多个）项目名称，选择时间范围，然后生成可视化的展示，并可设置时间流速。

Research direction
Explore how to use D3.js to create a 3D animated scatter plot with time slider. Consider using SVG transformations for perspective or pseudo 3D effects. Look into D3 force or existing 3D libraries like three.js as alternatives. Review the repository's existing data API to understand the input format.
