     - **Value -** The aggregation type to use for the values. The default is total (summing the values together).
   - **Histogram -** Converts the graph into a histogram. A histogram is a kind of bar chart that groups numbers into ranges, often called buckets or bins. Taller bars show that more data falls in that range.
