Not only can Pandas handle your data, it can also help with visualizations. Let's run through some examples of scatter plots.We will be using the San Francisco Tree Dataset.To download the data, click "Export" in the top right, and download the plain CSV. Colour points in a plot differently depending on a vector of values (2) I'm plotting the plot below using R's plot function. the above code used to plot two variables (column 3 and column 12), and each row is in 10 categories as indicated by column 14. Correlation plots, also known as correlograms for more than two variables, help us to visualize the correlation between continuous variables. Figure 5.5: Scatter plot with the shape aesthetic set to a custom value (left); With a variable mapped to shape, using a custom shape palette (right) 5.3.3 Discussion Figure 5.6 shows the shapes that are already built into R.
