Visualization

Your reading route

Visual disk browsers make storage structure easier to discuss, but the size of a rectangle does not tell you the value of its contents. This reading route connects treemap interpretation with a practical detail check. The guide uses a hypothetical example to show why a striking shape should lead to a path and a purpose, not directly to deletion.

Start by identifying the selected root and the meaning of the area and color encodings. Move from the visual pattern to a readable listing for any candidate that deserves attention. The GUI topic page extends that review to focus, selection, labels, and keyboard access. A useful interface should let you explain both what the chart includes and what its view leaves out.
