Fig. 1. Sampling from palettes of mark shapes, encoding channels, and scaffold shapes (left), the Diatoms technique generated 20 alternative glyph designs for an urban mobility dataset [8] (center), displayed as small permutables, in which we show a single data point (New York City) drawn according to each of the 20 designs. We highlight two of these designs as small multiples, where every data point is drawn the same way (right). In these two designs, a city's region, area, and population correspond respectively with the drop's fill color, size, and rotation in A and with the hexagon's fill color, rotation, and alpha level in B ; a city's bike, transit, and walk scores correspond respectively with the purple, brown, and pink waves' amplitudes in A and with the stars' rotations in B .
