The most immediately noticeable difference between a bar graph and a histogram is that the bars in a bar graph typically don't touch each other (other than in a grouped bar graph).

What is a histogram? A histogram is a basic bar graph that visually represents some set of data. In photography, it illustrates the pixels that make up your image in a two-dimensional graph.
