What do the bars mean in integers?
As with computing, mathematics uses the vertical bar in a variety of ways. For example, it can indicate the absolute value of a number, as in |-5| = 5. This means that the absolute value of -5 is 5. The vertical bar can also express divisibility.
Can a bar chart be used for numerical data?

Is bar chart for numerical data?
Bar charts plot categories, not numerical ranges, so the width isn't meaningful. To summarize, both histograms and bar charts are composed of bars, but that's really where the overlap stops. They have varying use-cases, display different types of data, and have specific formatting rules.
When you should use a bar chart
A bar chart is used when you want to show a distribution of data points or perform a comparison of metric values across different subgroups of your data. From a bar chart, we can see which groups are highest or most common, and how other groups compare against the others.
Best practices for using bar charts
First and foremost, make sure that all of your bars are being plotted against a zero-value baseline. Not only does that baseline make it easier for readers to compare bar lengths, it also maintains the truthfulness of your data visualization.
Common bar chart options
A common bar chart variation is whether or not the bar chart should be oriented vertically (with categories on the horizontal axis) or horizontally (with categories on the vertical axis). While the vertical bar chart is usually the default, it’s a good idea to use a horizontal bar chart when you are faced with long category labels.
Visualization tools
Most tools that can create visualizations, whether they be spreadsheets, programming libraries, or business intelligence tools, should be capable of creating basic vertical bar charts. Sometimes, options need to be checked or modified in order to follow best practices. However, for basic data exploration needs, any tool should be sufficient.
Origin
The word bar has its origin in the Ancient Greek word βάρος ( baros ), meaning weight. The unit's official symbol is bar; the earlier symbol b is now deprecated and conflicts with the use of b denoting the unit barn, but it is still encountered, especially as mb (rather than the proper mbar) to denote the millibar.
Usage
Atmospheric air pressure is often given in millibars, where standard atmospheric pressure is defined as 1013.25 mbar, 101.325 kPa, 1.01325 bar, which is about 14.7 pounds per square inch.
