Latitude (continuous measure, latitude geographic role assigned) Longitude (continuous measure, longitude geographic role assigned) Basic map building blocks: Columns shelf: They are listed in order from La Défense (Grande Arche) to Pont de Neuilly using the numbers 1 through 3 in the Order of Points column. In the example table above, there are three stations on line 1. This field is very important if you have more than two locations in a path, because it draws your paths in the desired order (you can think of it like connecting the dots). This column defines the point order and the direction in which the line is drawn from the first data point to the last data point on your map, which, in this example is the start and end of the metro line. Every location in line one contains the line group 1, and every location in line 10 Boucle contains the line group 10. For metro line 10 Boucle, the Line Group is 10. You will use this column to create your spider map.įor example, in the table above, there are two metro lines (1 and 10 Boucle), and each of those metro lines have a unique path ID listed in the Line Group (Path ID) column. In this example, the Line Group (Path ID) column is used to identify each unique path. Lineįor each path, there is a unique key or string, which is added to every location in that path. It also contains the additional columns Line, Station, and Traffic for added clarity and organization, but they're not required to build the map view. The first three metro stations for two metro lines are included in this example, and it contains the required columns Line Group (Path ID), Order of Points, Latitude, and Longitude. It contains metro traffic data for all metro lines in Paris, France. The following table is a snippet of the Transports data source, which is included in the Create Spider Maps in Tableau Example 1 Workbook (Link opens in a new window) on Tableau Public. A column with your location names (recommended, but not required).Latitude and longitude coordinates for every location.See The Order of Points column below for more information. Numbers to define the drawing order of each data point (location).See The Line Group (Path ID) column below for more information. To create this type of spider map in Tableau, your data source should include the following information:įor every unique path. Example 1: Metro station traffic in Paris, France See Create a visualization using MAKELINE. If your origin and destination data are on the same row, you can use the MAKELINE function to generate a line mark between two spatial points. Note: In the following examples, the data source has points that each have a unique path ID and are each on a different row.

There are several ways to create spider maps in Tableau. They are an excellent way to show the path between an origin and one or more destination locations. Spider maps are great for when you’re working with hubs that connect to many surrounding points. These types of maps are called spider maps, or origin-destination maps. You can create maps in Tableau Desktop that show paths between origins and destinations.
