Visualization of the artwork construction dynamics.

<p>(<b>A</b>) The visual report of the dynamics of an artwork progression, displaying rigorous tracking of events and states of the artwork over time. For example, stroke start and stroke end, the color and tool used for the stroke, its location in the page (in which quarter and whether in the boundary or center), the drawing pressure and direction. Idle periods are clearly seen, as well as erasing epochs of drawn objects. Snapshots of the artwork creation appear along the parameters temporal plotting. (<b>B</b>) Illustration of the interpretation of the visual report, which enables the reconstruction and formation sequences of objects in the artwork.
