A histogram is a graphical representation of data that shows the frequency or number of occurrences of different values in a dataset.
It is similar to a bar chart, but the bars in a histogram are typically positioned adjacent to each other, without gaps, to show the continuous nature of the data.
A histogram is used to display the distribution of a dataset, and to identify patterns, trends, and outliers in the data.
It can also be used to compare the distributions of different datasets, or to evaluate the effectiveness of data processing or analysis methods.
A histogram is a useful tool for exploratory data analysis and can provide valuable insights into the underlying structure of a dataset.
