2nd Visualization Assignment Use Tableau or Google Fusion Tables to create a set of visualizations Tableau only runs on Windows and Mac Fusion Tables runs on Windows and Mac Tableau Tasks Create a series of visualizations - 3 to 5 - and select appropriate display types. Create a dashboard with the visualizations that you created. Data Sets: same / similar data sets as used in 1st visualization (if rich enough) or you can select new data sets Fusion Tables Tasks Find interesting and unique and large data set. Prep data set so that it can be viewed using Fusion Table. Visualize data as a map. Customize visualization.

Tableau – Dimension versus Measure Tableau treats any field containing qualitative, categorical information as a dimension. Dimensions typically produce headers. Measure Tableau treats any field containing numeric (quantitative) information as a measure. Measures typically produce axes. Measure is a function of other Dimensions placed on the worksheet (e.g. Sum of “Sales” for every “State”). Can convert Measure to Dimension (using drag & drop). Headers Created when you place dimension on Rows or Columns shelf. Axes Created when you place measure on Rows or Columns shelf.

Tableau – Building Views / Visualizations Dragging Fields Visualize data by dragging fields from Data window to view. Dimensions add headers while measures add continuous axes. Types of Shelves Columns / Rows shelves: create rows and columns of data view. Filter shelf: exclude data from view. Levels of Detail shelf: show additional data. Color / Size / Shape shelf: encode the data in various ways. Show Me Suggests possible display types to use. Map Columns for Longitude | Rows for Latitude.

Fusion Tables – http://www.google.com/fusiontables/ New Look versus Classic The Classic look These classic features are not yet available in the New look: Geocoding correction / KML preview Map charts (a Labs visualization) Intensity maps and heatmaps Comments on rows, cells, or columns  You can use Help > Back to classic at any time.
