Steps to Reproduce

Hello,
I use sunburst chart and I have problems with decals.
I made some check and I'm quite sure that decal definition within series.data doesn't override the base definition:

var data = [
{
name: 'Parent',
children: [
{
name: 'Base decal',
value: 1
},
{
name: 'Changed decal',
value: 1,
itemStyle: {
decal: {
symbol: 'none'
}
}
}
]
}
];
option = {
aria: {
enabled: true,
decal: {
show: true,
decals: {
symbol: 'circle'
}
}
},
series: {
type: 'sunburst',
data: data,
radius: [0, '90%'],
label: {
rotate: 'radial'
}
}
};

Thank you, regards,
Fabrizio

Current Behavior

"series-sunburst.data.itemStyle.decal" doesn't override base setup "aria.decal. decals"

Expected Behavior

"series-sunburst.data.itemStyle.decal" must change the base setup "aria.decal. decals"

Environment

- OS:Centos
- Browser:Firefox
- Framework:

Any additional comments?

Yes, several bugs and inconsistencies.

data.children.itemStyle.decal does not work at all.
data.itemStyle.decal works for pie, but not for sunburst
area.decal.decals overwrites all others in sunburst
series.itemStyle.decal is overwritten by data.itemStyle.decal in pie as expected

@Aman1919 Thanks for the help! setVisual is already done in aria.ts, which handles for all series.
