Doing a google search or google image search from a dashboard is another action that we should try. So, what is the benefit of it? In the visualization, users can explore news stories or related images by following links provided within the Tableau dashboard for thousands of different data points.
Here is a good example provided by the following link:
https://public.tableau.com/shared/BCTCC8K6H?:toolbar=no&:display_count=yes
Clicking on any location will open a new browser with a Google Image Search for that location. Then how to do it:
- Google search the images of the locations and copy the URL that appears in the browser. (e.g: the link of Kansas City is https://www.google.com/search?q=kansas+city&source=lnms&tbm=isch&sa=X&ved )
- Go to any of the dashboard ‘Dashboard>Actions> URL’. Paste the URL you just copied. Replace the actually useful portion of the URL for the query, which is the text immediately following the “?q=”, with a field from your data.
- Add the field from your data source (e.g: I want to change the city location) , for which the information you want to change interactively by clicking the arrow that appears next to the empty URL box.
- Finished! If you click on any location point on the map, a Google Image search is executed with the name of that city (from my underlying data) as the search query.
