I want to share the reading/resource list in my data visualization course; the list breaks into six sections: intro to data viz, choosing the right chart, designing a nice-looking visulization, communicating your message, tools/tips, and resources. This list will be a work in progress and all suggestions are welcomed.
Intro to data visualization
A Quick Illustrated History of Visualization: Data visualization has its roots in a long historical tradition of representing information using pictures in ways that combine art, science and statistics.
Why Data Visualization Matters? Data visualization reveals unnoticed information, especially in large data sets; gives answers faster; and helps journalists investigate cause-effect relationship.

Data Art vs. Data Visualization: Data art refers to visualizations that strive to entertain or to create aesthetic experiences with little concern for informing; data art is harmful when it masquerades as data visualization.
Choosing the right chart
Visualization Options Available: A detailed introduction of 21 popular chart types, in six categories, by Many Eyes.

Present your data in a scatter chart or a line chart: Scatter charts and line charts look very similar, especially when a scatter chart is displayed with connecting lines. However, there is a big difference in the way each of these chart types plots data along the horizontal axis (which is also known as the x-axis) and the vertical axis (which is also known as the y-axis).

The result is an exciting gallery of infographics that tell you nothing.
