Design 1 · Open versus closed, always both halves
Donut with the percentage closed in the centre, a clickable legend with counts, and a note that the status filter is ignored.
Design 2 · Versions tab
Horizontal stacked bars per version, done against remaining, a percentage label and the due date, ordered by due date.
