             Description                    It is a combination of a bubble chart, data visualization and a map. It is
                                            used to visualize location and proportion using circles over geographical
                                            regions with the area of the circle being proportional to its value in the
                                            dataset.

             Suitable for which type of data? It is good for comparing proportions over geographic regions without the
                                            issues caused by regional area size. For example, showing the earthquake
                                            prone areas in a country, geographical distribution of whales in the northern
                                            hemisphere, number of tigers in the national parks of India.



                    Visualise Data using Visualisation Tools

            We can use any of the previously discussed data visualisation tools. In this case, we are using Tableau Public. To
            use this software, we need to download it first from the following URL (Uniform Resource Locator):

            https://public.tableau.com/en-us/s/download

            Once the downloading is completed, install it on your computer. After installing the Tableau Public, perform the
            following steps:

            1.  Now, you need a large amount of data to visualise. You can take the data from any government portal. In this
               case, we are taking data from the public portal: https://aishe.gov.in/aishe/home
               The home page of the website appears.

            2.  Hover the mouse on the Directory of Institutions menu. A sub menu appears.

            3.  Click on the Universities option. The Directory of Institutions web page will appear.
