What problem does this feature solve?
以svg渲染矩阵树图，当某条数据所占比例特别小的时候，这个时候该条数据的宽或者高就会比较小，就会造成文本不显示或者显示不美观，如果能拿到每条数据所在矩阵的宽高，就可以在label的formatter里面更加灵活的去以更加美观/完整的方式展示文本信息
What does the proposed API look like?
label: {
formatter: (params) => {
// params里面包含当前数据的矩阵宽高
}
}

TITLE
treemap gets the width and height attributes of the matrix where the data is located
BODY
What problem does this feature solve?
Rendering matrix tree map with svg, when the proportion of a piece of data is particularly small, this time the width or height of the data will be relatively small, will cause the text does not show or display is not beautiful, if you can get the width of each data in the matrix, you can be more flexible in the label information to display text information in a more beautiful / complete way
What does the proposed API look like?
label: {
formatter: (params) => {
Params contains the matrix width and height of the current data
}
}

@ctrlands echarts 5.0 开始可以在
labelLayout配置中根据矩形高宽配置字体，参考这个例子 https://github.com/apache/echarts/blob/master/test/treemap-obama.html#L343
