Chart Generator

数据可视化图表生成器,通过 scripts/chart.sh 生成ASCII图表或HTML文件。

为什么用这个 Skill? / Why This Skill?

  • 即开即用:一条命令直接出图,不需要安装matplotlib、echarts等复杂依赖
  • 双输出:终端ASCII图表(方便命令行查看)+ HTML文件(方便分享和嵌入)
  • 迷你趋势图:Unicode sparkline一行搞定趋势展示
  • Compared to asking AI directly: produces actual runnable chart output (ASCII art + HTML files), not just code snippets you'd need to run yourself

使用方式

脚本路径:scripts/chart.sh(相对于本skill目录)
