Good day, david-b-goodman.
For now there's no option to create a graph in QuickBooks Online. However, the Business Snapshot report has a graph of your income and expenses. Just go to the Reports menu and type in Business Snapshot in the Search bar.
You can also export the other reports to Excel. Then, create your graph in the Excel application. Just click the Export icon in the upper-right hand corner of the report and select Export to Excel.
Just in case you have not completed your year-end tasks, you can check out this article for additional guidance and reference: QuickBooks Online Year-end Guide And Checklist.
