用在线工具做一张桑基图 →It represents flows among nodes of a network. Nodes are represented as rectangles, the height represents their value. Flows are represented with curved lines whose width is proportional to their value.
在 RAWGraphs 里制作桑基图只要四步:①把 Excel / CSV 表格数据复制粘贴进工具;②在图表列表里选择「Sankey Diagram」;③把左侧的数据字段拖到右侧对应的映射区(如维度、数值、颜色);④在 Customize 里调颜色与标签,最后导出 SVG 或 PNG,SVG 还能放进 Illustrator 继续精修。全程数据只在浏览器本地处理,不上传。
