Histogram and Density Plot

Introduction to histograms in ggplot2

A histogram is a data visualization technique in statistics and data science that summarizes data by representing data points organized into user specified ranges or bins. In other words, we can easily interpret the total number of data points falling within specified bins, i.e., the range of values in a histogram. Similar to bar graphs, rectangular blocks are used in a histogram to display data.

Note: Unlike a vertical bar chart, the bars of a histogram don’t have gaps between them.
