The report on HTML5 and RUI homepage is displayed as "Bar" chart type. However, you have set the default chart type as "Bubble" in Business Analysis work center.
Reproducing the Issue
You have set the default chart type of this report as "Bubble" in Business Analysis work center.
Then assign the report (report view) to your homepage
You will see the report is displayed as "Bar" chart type, not "Bubble" on your HTML5 homepage and RUI homepage.
This is a standard system behavior.
The system does not support “bubble” on both HTML5 homepage and RUI homepage for current version.
However, we are planning to support additional chart types on RUI homepage, including Bubble chart in future release.
