这个图表的名称是什么？

Question

这种图表有具体的名称吗？ JavaScript 图表库有什么？

Answer 1

查找 treemaps / treemapping。 Wikipedia 是这样描述他们的：

"In information visualization and computing, treemapping is a method for displaying hierarchical data by using nested rectangles. […]

Treemaps display hierarchical (tree-structured) data as a set of nested rectangles. Each branch of the tree is given a rectangle, which is then tiled with smaller rectangles representing sub-branches. A leaf node's rectangle has an area proportional to a specified dimension of the data."

利用此技术的一个著名工具是 WinDirStat。他们的网站也将这种可视化称为树状图。

鉴于这个术语，您应该能够轻松找到一个 JavaScript 库，只需执行 a web search 即可生成它们。（我不能推荐以下任何一个，因为我没有使用过它们，但是链接的 Google 搜索找到 jsTreemap、Plotly.js、Google 图表和其他一些，在第一个结果页。)

如果您对这些图表背后的算法感到好奇，可能会对这些论文感兴趣：

Answer 2

它被称为 treemap, and ZingChart 是一个拥有它的 JavaScript 图表库。这是绘制分层数据图表的有用方法。它还允许用户交互，因为用户可以进一步向下钻取树状图。查看下面的演示。

var myConfig = {
    "graphset":[
        {
            "type":"treemap",
            "plotarea":{
                "margin":"0 0 30 0"
            },
            "tooltip":{
                
            },
            "options":{
                
            },
            "series":[
                {
                    "text":"North America",
                    "children":[
