5. © Anselm Spoerri 2 nd Visualization Assignment Use Tableau or Google Fusion Tables to create a set of visualizations –Tableau only runs on Windows –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 1 st 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.

7. © Anselm Spoerri Tableau – Dimension versus Measure Dimension –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.

8. © Anselm Spoerri 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.
