More dimensions through multiple visual<br />
encodings <strong>and</strong> small multiples<br />
You can increase the number <strong>of</strong> dimensions (variables) that can be viewed<br />
simultaneously in two ways: 1) by using multiple visual encodings, <strong>and</strong> 2) by breaking<br />
the data into a series <strong>of</strong> small graphs that share common scales so they can be<br />
compared to one another. In the bubble plot on the right, we can view four variables at<br />
once: the rate <strong>of</strong> property crime based in position along the X-axis, the rate <strong>of</strong> violent<br />
crime based on position along the Y-axis, the population <strong>of</strong> states based on the size <strong>of</strong><br />
the bubbles, <strong>and</strong> the region in which each state resides based on color. The series <strong>of</strong><br />
small multiples on the left allows us to revenue, costs <strong>of</strong> goods sold, <strong>and</strong> gross pr<strong>of</strong>it<br />
along the Y-axis, quarters along the X-axis, <strong>and</strong> different product lines per graph. If we<br />
tried to display all <strong>of</strong> this information in a single graph, it would be far too cluttered <strong>and</strong><br />
difficult to perceive.
