I have created polygons files of several Canadian cities to use in Tableau. They are either Electoral Districts or Wards and the source shapefiles comes from the following cities Open Data Portals:

You can access these polygon points csv files from my public Dropbox here: Polygons for Tableau

City of Ottawa Wards

If you want to know how to create and prepare polygon maps from shapefiles to use in Tableau, I recommend the following articles:

Keep you posted on new files from other Canadian cities…

  • Presentation slides from my session “Building Network Graphs with Tableau” at the Ottawa Tableau User Group Meetup – Thanks to everyone who attended.

    To build the network graph demo, here is the Excel Workbook with the sample data for download:
    Network Graph Sample Data (Microsoft Excel) – AsterixGraphData_Tableau.xls

    To implement network graphs in Tableau, Data preparation is key!

    tableau_ng_00

    Let’s quickly go through the steps and create a network graph with this very small sample dataset;

    To start, drag the “LineY” attribute to the Rows shelf and the “LineX” attribute on the Columns shelf. Set the Mark type to “Circle” this will render a basic scatterplot.

    tableau_ng_01

    Add the “CircleY” attribute to the Rows shelf as a Double Axis (right click on the Axis and click “Dual Axis”), and then synchronize the two Y axes (right click on the Axis, and click on “Synchronize Axis”)

    tableau_ng_02

    Next we need to format the Tableau Mark cards to show “Multiple Mark Types“. Go to the “CircleY” Mark card and set Mark type as “Pie“. Drag the “NodeName” attribute on Label and “ID” on Color on the Mark card – each pie slice represents a connection (transaction)

    tableau_ng_03

    Then cycle to the “LineY” Mark. Drag the “ID” and “Relationship” attributes on Detail on the Mark card. Set the Mark type to “Line”. Tableau will connect the dots… and Voilà! A simple Network Graph. You can resize the LineY series to make lines thinner.

    To further enhance your visualization you could add a summary table, provide filters, and modify the tooltips.

    Have fun!
