Currently the Import Status charts are not natively available in Notion, unfortunately. As a workaround for now, the status needs to be exported from Notion and pasted into a Google Sheet, and then this needs to be embedded into your Notion page.
The first activity is a regular task, while the latter is a one-time setup activity.
The update of the charts is an export/import exercise.
In Notion go to the Process Import Catalog and select "Export" from the "three dot" menu. In the popup, select "Markdown & CSV" and press Export.
You will download a ZIP file that includes a CSV file. Open it in your local spreadsheet program.
The activities listed below need only to be done once to setup your dashboard in your Notion instance.
