This screen image has the heading ‘Visualizations: OpenLearn Course Units Treemap (DEMO)’. Here a large rectangle is once again divided into several smaller ones which are then sub-divided again into many smaller rectangles. Each of the medium rectangles is a different colour (pale shades of turquoise, blue, peach, yellow, purple, green) and labelled with a different subject area (science and nature, society, mathematics and statistics, arts and history, education and lastly IT and computing). Along the top of the window is a set of headers with the explanation ‘Treemap Hierarchy (Drag to Reorder)’. From the left the headers are ‘Subject Area’, ‘Original Course’, ‘course Code’, ‘Description’, ‘Course Title’, ‘Tags’.
