in this you learned to generate data sets and create visualizations of that data you learned to create simple plots with matplotliband you saw how to use scatter plot to explore random walks you learned to create histogram with pygal and how to use histogram to explore the results of rolling dice of different sizes generating your own data sets with code is an interesting and powerful way to model and explore wide variety of real-world situations as you continue to work through the data visualization projects that followkeep an eye out for situations you might be able to model with code look at the visualizations you see in news mediaand see if you can identify those that were generated using methods similar to the ones you're learning in these projects in we'll download data from online sources and continue to use matplotlib and pygal to explore that data generating data
