When reading graphs, always look at the axes to see what information the graph is about.

Also always look at the title of the graph to give you a clear idea of what the graph is about.

Histograms vs Bar Graphs

There is a difference between a Bar Graph and a Histogram.

A bar graph is great for categorical data (if your collected data is in the form of words).

A histogram is better for numerical, continuous data (if your collected data is in the form of numbers).
