Bar chart diverging
Butterfly chart; tornado chart (for specific styles)
A diverging bar chart is designed to highlight contrasts or polarities in data. Two sets of data series are displayed side by side with bars going in opposite directions from a central point. Primarily used to compare positive and negative values of a single variable across different categories. There's some similarity with the spine chart.
Use for data with both positive and negative values and use distinct colours for each. Align bars around a logical central value (e.g. 0 or neutral), and clearly label axes and categories. Don't use if your data has a natural order, such as chronological data.
1. To visualise 'likert scale' responses (e.g. from strongly agree to strongly disagree).
2. To highlight profit versus loss across business segments.
Rate your agreement with the following statement: 'Remote work is more productive than in-office work.'
