The chart is a useful way to display initiatives, but could use some more customization options, specifically the ability to increase font size as the visual is almost unreadable when exported.

This is currently possible through the charts page. You can access a similar chart via the Views dropdown -> Related views -> Scatter chart: Initiative value and effort. You can then select the Format chart icon -> Customize option to customize the size and color of the text shown.
While we are unlikely to make updates to the Initiative chart, we hope that the flexibility noted on the Charts page will help with your use case.
