echarts5.x 词云图使用（[ECharts] Unkown series wordCloud）

背景

起先还庆幸自己 echarts 用的是 5.x 的版本，似乎可以少些麻烦

结果发现按照 echarts-wordcloud 描述的操作歩鄹，词云图并出不来……

打开控制台，出现了报错：log.js:62 [ECharts] Unkown series wordCloud

估摸着就是引用不对，翻了几遍文档及网上的案例，都是那么简单的几步，并没有找到什么遗漏的操作

没有办法，就试着看看是不是引用有问题，我找了下 node_modules 目录，发现并没有 wordCloud 相关的包，居然引用也不报错？打印出来发现 undefined，找不到返回 undefined 似乎逻辑上也没什么问题……

没装上就重新装一下咯，结果发现 cnpm install echarts-wordcloud 秒过，但依赖包并没有下载过来，npm install echarts-wordcloud 等了半天装了一堆毫不相干的东西，还报了个错……

装不上……那就复制源码本地保存一份咯……

去到 echarts-wordcloud 的 github，复制了 echarts-wordcloud.min.js 代码，存在了 utils 目录下，然后用相对路径引入进来，发现就行了……

预期效果

自定义形状

形状可以从 iconfont 找，下下来的图片可以通过在线工具转成 base64 格式然后在代码里引用

• 图片最好选纯黑色填充，120px 左右大小（我试了好多种图片，只有2种成功了，匹配度还不是很高，后续用到了再探索吧……）
• 参考：关于Echarts词云图自定义形状如何实现

let maskImage = new Image();
maskImage.src =
