forcing client rendering with :render=true about tableau-scraping HOT 2 CLOSED

@sethvincent Hello, sorry for the late reply, I didn't notice data rendered server side when I go to the dashboard: https://dashboards.doh.nj.gov/#/views/DailyConfirmedCaseSummary7_22_2020/ConfirmedCases.

Which selectable data do you want to retrieve ?

from tableau-scraping.

@sethvincent I think I've already encountered this call, it's present in server side rendered tableau url like this one: https://public.tableau.com/views/CMI-2_0/CMI?:showVizHome=no when you click on the map or in the table.

The thing is that you need to send the mouse coordinate in the body like this:

worksheet: US Map - State - CMI
dashboard: CMI
vizRegionRect: {"x":620,"y":85,"w":0,"h":0,"r":"viz"}
mouseAction: simple
zoneId: 248
zoneSelectionType: replace

There are images that are rendered in the html like this:

It would be difficult in this case to iterate over all the states by their respective x/y position (not impossible though)

The same applies for the tables which are rendered as images like:

We would need to guess the x/y position.

For now, the safest (and not too hacky) trick to get data from server side rendered tableau url is to search for filter requests that return actually client side rendered data like in #13. Also documented here. A good example is also this: https://stackoverflow.com/questions/66238702/how-can-i-extract-values-from-tableau-dashboard/67222561#67222561

But sometimes, there is no filter set by default or the filtered result is always server side rendered, in this case I don't know how we can get the data without OCR or other image analysis techniques.

In your case, I'm pretty confident you can access the data directly, let me know if you're stuck with a server side rendered url
