Timespan ranges with dots and direct labels

Dumbbell graphs display the relationship between two data points for multiple categories by connecting them with a line. It effectively shows the difference or change between these two values for each item, allowing for easy comparison of magnitudes and variations across the dataset. This visualization is useful for highlighting shifts or disparities.
