How to Create Bar Chart using React Bootstrap ?

A bar plot or bar chart is a graph that represents the category of data with rectangular bars with lengths and heights that is proportional to the values which they represent. The bar plots can be plotted horizontally or vertically. A bar chart describes the comparisons between the discrete categories. One of the axes of the plot represents the specific categories being compared, while the other axis represents the measured values corresponding to those categories.
