I found a way to solve this, however it is not elegant: whether in the data
provider API code or in the middle data processing, define data directly by
adding "itemStyle"and"borderColor" field at each node data, which means we need
to modify backend data structure to achieve this goal. The data would look like
this:
```javascript
data = {
name: 'prj-investran-ug',
value: 0.5,
name2: 'https://www.google.com',
"itemStyle":{"borderColor":"red"},
children: [
{
name: 'prj-security-ug',
children: [
{
name: 'converters',
children: [
{ name: 'Converters', value: 721
,"itemStyle":{"borderColor":"red"}},
{ name: 'DelimitedTextConverter', value: 4294
,"itemStyle":{"borderColor":"green"}}
]
},
{
name: 'DataUtil',
value: 3322
}
]
},
{
name: 'display', value:1,
children: [
{ name: 'DirtySprite', value: 8833 },
{ name: 'LineSprite', value: 1732 },
{ name: 'RectSprite', value: 3623 }
]
},
{
name: 'flex', value:3333,
children: [{ name: 'FlareVis', value: 4116 }]
}
]
};
```
is there any other way more elegent?
