chart type change on published bookmarks

Hi bsheffer ，

According to the design of the bookmarks, it will only save the following content:

• The current page //When there are multiple pages, bookmarks only save the content of the current page
• Filters
• Slicers, including slicer type (for example, dropdown or list) and slicer state
• Visual selection state (such as cross-highlight filters)
• Sort order
• Drill location
• Visibility of an object (by using the Selection pane)
• The focus or Spotlight mode of any visible object

Create report bookmarks in Power BI to share insights and build stories

So it doesn't save changes to the chart type. 
There's a workround:
Create two visuals and save their visibility properties using bookmarks, which can then be used to switch between them.
