[Bug] visualDimension has no effect on treemap

### Version

5.6.0

### Link to Minimal Reproduction

https://codepen.io/jbdesbas/pen/ogNdeBM

### Steps to Reproduce

1. Create a treemap chart with multi-dimension data (eg : ` data = [{value: [ 100, 50, 'a' ]}, {value: [ 200,50 ,'b' ]}, {value: [ 300,50 ,'b' ]} ] `
2. Try to select dimension to represent (0 or 1)

```js
data= [
{ value:[10,'n1',100,50]},
{value:[10,'n2',200,50]},
{value:[10,'n3',300,50]},
];

option = {
series:[
{
name:"test",
type:'treemap',
data: data,
visualDimension:2,
}
],}
```

### Current Behavior

The `visualDimension` parameter seems to have no effect, the dimension 0 is always used for area size.

### Expected Behavior

The `visualDimension` parameter should allow to select a dimension as area size.

### Environment

```markdown
- OS:Pop OS
- Browser: Firefox 129.0.2
- Framework:React@18
```
