Streamgraphs
What (Data) Multidimensional table: one quantitative value attribute (e.g. counts),
one ordered key attribute (time), one categorical key attribute.
What (Derived) One quantitative attribute (for computation of layer ordering).
Why (Task) Find trends.
How (Encode) Use derived geometry showing artist layers across time, layer height
encodes counts.
Scale Key attributes (time, main axis): hundreds of time points. Key attributes
(artists, not always over entire time axis): dozens to hundreds.
