How can I pull data from Wikipedia and start visualizing without having to download that data into an excel file or a text file?
e.g. very simplistic example would be: Aetna - Wikipedia If I simply want to plot a line chart of the revenue and net profit, how can I do that?
You can try copying and pasting the data into Tableau Desktop from the Wiki page.
Highlight the data right click and select copy. Right click in the Tableau Desktop workbook, select paste, the data will be added as a new data source with the name "clipboard data<numeric string>".
Hope this helps!
