Important Features of a bar chart
Bars: The chart consists of rectangular bars that represent different categories or data points. The length or height of each bar represents the value or magnitude of the data it represents.
Axes: A bar chart typically has two axes: a vertical axis (y-axis) and a horizontal axis (x-axis). The y-axis represents the values being measured or compared, while the x-axis represents the categories or groups being compared. In this case, we have categories of vehicles or type of vehicle and number of vehicles.
Labels: The chart should have clear and informative labels for both axes, indicating what is being measured or compared and the units of measurement, if applicable. It may also include labels for individual bars or categories.
Title: A bar chart should have a descriptive title that summarizes the purpose or main message of the chart.
