You can now display your numeric attributed data using Pie maps. Use the Base Symbology tool to choose which attributes from your vector file you're interested in, then represent the proportions of these components with colored pie slices. Size the pies proportionally or use a fixed size, customize colors, labels, position and formatting. This is a great way to display demographics data from the US Census, sample concentrations from your recent field season, or even geographically-varying survey responses.
