Guidelines
Use When
- Representing information tied to specific countries, such as global market performance.
Don′t Use When
- Displaying data where precise comparison is more important than its geographic placement. Instead, use a Horizontal Bar chart or a Vertical Bar chart.
Visual Language
- Never use colors other than those defined in the visualization palette.
- Always use the relevant color orders and meanings from the visualization palette. Common color sets to use with the Geographic Map would be Performance and Valuation.
- The chart and its legend should always have seven colors, two base colors, two tints of each base color, and one neutral color. These tints can be determined by each implementing team, but they should be based off of existing color constants from the visualization palette.
For example, when representing valuation, use $mds-visualization-color-valuation-under and $mds-visualization-color-valuation-over as the base colors for each color set, then tint those colors to create the two necessary tints (i.e., 100% [base color], 66% [tint 1] and 33% [tint 2]). Use $mds-visualization-color-valuation-fair to represent the central, neutral value.
Responsiveness
- Geographical maps will resize to fill the available space until they reach a width of
320px. - The legend’s width is fixed and decreases at a component width of
320px.
Editorial
- Include the unit or increment in legend labels.
- Strive for a short, succinct label header for the chart which clearly describes the data.
