Performing data analytics and visualizing data using R and open data
Data visualization courses
CS171 :This is a great introduction for someone who is interested in learning about data visualization. The course videos are uploaded every year. Student projects are listed under projects and is a great way to learn about some innovative ways in which you can visualize data.
Flowing data : I love this website. In fact one of the very reason i started using R was because of Nathan Yau’s R tutorials. I visit his website almost every day as he posts some cool visualizations on a daily basis. He has tutorials some of which are free and some are paid. The annual membership is worth every penny.
