aoliaoliao opened a new issue, #18256:
URL: https://github.com/apache/echarts/issues/18256
### What problem does this feature solve?
I know echart has done a lot on accessibility, thanks a lot.
The purpose of this issue is want to know whether the Echart team has plans
to support further improvement of the accessibility function, so that users can
access specific elements inside the chart and operate them through tab, arrow
keys and space keys.
### What does the proposed API look like?
This is just an idea, take bar chart as an example.
```javascript
var myChart = echarts.init(document.getElementById('main'));
option = {
aria: {
show: true
},
series: [
{
name: 'Referrer',
type: 'pie',
data: [
{ value: 335, name: 'Direct Visit', ariaLabel: 'aria label for
Direct visit' },
{ value: 310, name: 'Email Marketing' , ariaLabel: 'aria label for
Email Marketing' },
{ value: 234, name: 'Union Ad' },
]
}
]
};
```
