If the intervals are of different width, then it is a histogram.
a bar graph
The graphical representation you are describing is known as a histogram. In a histogram, the vertical rectangles (or bars) represent the frequency of data within specific intervals (or bins), and the centers of the bases of these rectangles align with the class marks of the data. The height of each rectangle corresponds to the frequency of observations within each class interval, visually illustrating the distribution of the dataset.

The Key?
The intervals that the bars represent are touching each other.
a bar graph
A histogram is a chart comprising bars but, unlike an ordinary bar chart, the widths (intervals) of the bars are different and their heights represent the frequency densities, not frequencies.
Oh, dude, it's like this: a histogram is like a bar graph that shows the frequency of data within specific intervals, while a frequency polygon is a line graph that connects the midpoints of the intervals in a histogram. So, it's like the difference between drawing bars and connecting dots. Cool, right?

Histograms are arranged by dividing the data range into intervals, known as bins, which are typically of equal width. The frequency of data points within each bin is then counted and represented as vertical bars, with the height of each bar corresponding to the frequency of data in that interval. The bars are placed adjacent to one another to visually depict the distribution of the dataset. The x-axis represents the bins, while the y-axis indicates the frequency or count of data points.
When marimba bars and columns vibrate at the same frequency, resonance occurs. This amplifies the sound produced by the marimba bars as the columns enhance the vibrations. Resonance is a natural phenomenon that magnifies vibrations when objects vibrate at their natural frequency.
In a bar graph, the height of the bars is relative to the frequency. In a histogram, the area of the bars is relative to the frequency. Because it deals with area, the label on the y-axis is "frequency density" rather than just "frequency"
A histogram is when the bars are touching and it graphs what you have on your frequency table.

Typically, climate graphs use blue bars to represent precipitation, red bars to represent temperature, and black lines to represent average temperature.
