For free, point-and-click data visualization, try the following:
Plotly: Create a wide range of static graphic visualizations, or interactive graphics for sharing online. Allows 'forking' and social editing of public visualizations. One private visualization is free; multiple private visualizations require a paid subscription. Check out the tutorials at https://help.plot.ly/
Datawrapper: Create univariate or time series visualizations from common types. Datawrapper is used by news media outlets, such as the UK's The Guardian; readers will notice a familiar look and feel. Unlimited static charts can be created for free, but exporting charts to anything other than PDF form requires a paid subscription.
Infogram: Upload your data, create, and share an infographic online.
Raw: Create web-based visualizations from a gallery of common chart types, all without uploading your data anywhere. Visualizations are created in your web browser without moving data off your local data storage. Visualizations can be exported as graphics files or shared online via HTML code.
Tableau: An extensive software application for data management, analysis, and visualization. Download the 'public' version of Tableau to your desktop computer.

Please note: There is a file type conflict between GVSU and infogr.am. The data files are saved as .txt files (GVSU does not allow the .csv file extension), but infogr.am expects csv files to have a .csv file extension and not .txt! So you'll need to rename these datafiles before uploading to infogr.am. The .txt file extension works fine on the other sites.
