Piechart rendering issue when column selected as 'key' is changed

Pie chart isn't rendered properly if we change key(domain) at runtime
Steps to reproduce:

• Create a built in pie chart visualization using an sql table with columns, say Job, Balance and Education.
• Set Job as key and sum(Balance) as values
• Delete key Job
• Set column Education as key
• Notice the empty spaces in chart

Paragraph used:

%sql
select * from bank
limit 20
