A Bullet graph is a single thermometer like visualization. They are used to compare the numeric value with a target value. The dark line in the middle of the graph indicates the value of the variable, while a vertical line is also there, which indicates the target.
Why do you need it?
A bullet graph takes less space when we compare them to dashboard gauges or meters. They are simple in application and effective to use. They don’t look clustered when used in bulk to represent different variables.
What kind of data you can visualize with it?
A single numeric-related data with a target is the best match with this graph. Assume you have the dataset of sales of a shop in a month. Then you can use this graph to visualize sales and set a target to the vertical line in the visualization. This will help you know is the target achieved or not.
