I need help with this burndown chart.

This burndown chart will show work completed (or not) on a weekly basis and need a kanban board to populate it. Wk 0: not all of the work was complete Wk 1: the work was "caught-up" Wk 2, 3, and 4: work is on track! Wk 6 and 7: not all of the work is complete Wk 8 and to the end: back on track You may not need all 12 weeks To maintain the graph, delete rows from the center; such as rows 12 and 13 or as appropriate. You may need more than 12 weeks To maintain the graph, insert rows in the center; such as between rows 12 and 13 or as appropriate. Update the Weeks number in column A
