Returning the selected string value from selection_single

[JuliusSempio]

Good day. I've been wrapping my head for hours about solving this issue by searching for the solution online, to no avail. So I decided to try to directly ask from Altair devs.

I am trying to automate the generation of the title of the scatter plot for convenience purposes, but I can't find proper documentation on accessing the selected value in the selection_single dropdown component. The following screenshot should give the idea on what I am trying to achieve.

Any help will be appreciated :)

To get the string value in the title, Vega-Lite would need to support the use of parameters in title but this is not yet supported as per vega/vega-lite#7365 (comment)
