              We can see from the above graph that car sales started dipping from April and sales reached the lowest point in June.
              Line graphs are useful for making comparisons between different datasets and can tell the changes in both long and
              short terms, with even small changes over time.


              Bar Chart
              A bar chart (also known as a bar graph) is a graphical tool that uses bars to compare data between categories.
              The length of the bar is directly proportional to the value it represents. The bars in the diagram can run horizontally or
              vertically and are the same width. Let us consider the number of Covid-19 vaccinations administered till a particular
              date in September 2021:
