Lollipop chart; high-low chart

This is a chart that uses dots and connecting lines to compare two sets of values across different categories or time points. It's a simple way to show the range of data (minimum–maximum). The chart can be shown horizontally or vertically.

Can be used to visualise differences between two different points in time, or to compare different viewpoints (e.g. one dot for one demographic group and another for a different group). Limit categories to avoid overcrowding. Use contrasting colours for the bars and the dots.
