G6.30: When animation is used in a visualization, aim for motion in the range of 0.5–4 degrees/second of visual angle.

G6.28: Consider using a treemap to display tree-structured data where it is only necessary to display the leaf nodes and where it is important to display a quantity associated with each leaf node.
G6.29: Consider using a node-link representation of a tree where the hierarchical structure is important, where internal (non-leaf) nodes are important, and where quantitative attributes of nodes are less important.

G6.27: Use small, closed shapes to represent point entities, such as cities, that appear small on a map. Use color, shape, and size to represent attributes of these entities.

G6.25: Use closed contours, areas of texture, or areas of color to denote geographic regions. Use color, texture, or boundary style to denote the type of region.
G6.26: Use lines to represent paths and linear geographic features. Use line color and style to represent the type of linear feature.

G6.24: As an alternative to arrows to represent directed relationships in diagrams, consider using tapered lines with the broadest end at the source node.

G6.23: Use connecting lines, enclosure, grouping, and attachment to represent relationships between entities. The shape, color, thickness of lines, and enclosures can represent the types of relationships.

G6.22: When developing glyphs, use small, closed shapes to represent data entities, and use the color, shape, and size of those shapes to represent attributes of those entities.

G6.21: In order to minimize the amount of learning needed to understand a visualization, make every effort to standardize the mapping of data to visual patterns within and across applications.

G6.20: To display discrete data with more than four dimensions, consider using a color-enhanced scatterplot matrix in combination with brushing.
