   Hi @linssen, sorry for the late reply.
   
   The configuration of the theme is very similar to the option. The only difference is series in theme is described in a map.
   
   For example:
   
   A typical option is : 
   ```js
   option = {
     series: [{
        type: 'bar',
        itemStyle: { color:  }
     }]
   }
   ```
   
   In theme, it needs to be:
   ```js
   theme = {
     bar: {
        itemStyle: { color:  }
     }
   }
   ```
   
   Besides this tiny difference, all the configurations in option can be described in theme, it will override the default value provided by echarts. Also, it can be override by the user option.
   
   PS: @Ovilia did a visual theme builder. But currently, the UI is still in Chinese. https://www.echartsjs.com/theme-builder/
