Creating visualizations

For creating a visualization, we need to click on the Visualize link on the left-hand menu, which will open a page. We will display a list of visualizations, if we have already created any; otherwise, there will be a page with a Create a visualization button in the middle. So, for creating a new visualization, we need to click on this button:

Now, we need to choose the visualization type from the Select visualization type screen. There are multiple types of visualizations, such as the ones shown in the following screenshot:

Now, we need to select the visualization type first by clicking on the visualization type box. But before selecting the right visualization type, we need to understand the data. By seeing the data, we can get the best way to depict it through visualization. For example, if we have a single dimensional data over time, we can use a histogram, but if we have related data, such as the number of votes acquired by each party in an election, we can use a pie chart. Bar charts can be used if we have two-dimensional data, such as subject name and numbers in each subject. Scatter charts can be used to scatter a point against two axes; for example, a house area and price can be easily plotted on a scatter chart. In this way, we can see our data, think, and then decide which is best suited to be displayed on the chart through visualization.
