Why is histogram a graph of bars that are together?

A histogram consists of bars that are adjacent to each other to represent continuous data in intervals or "bins." This design emphasizes the distribution of data points across the range of values, indicating how frequently each range occurs. The closeness of the bars visually reinforces the idea that the data is part of a continuous spectrum, rather than discrete categories. This helps in understanding patterns, trends, and the overall shape of the data distribution.
