Hello Nicole,
First of all, nice viz!
I like the shapes you use.
I don't think there's a ready for use function for your requirement.
But one workaround I can think of is,
1) use a parameter to select a point instead of click.
2) write a long long calculated field (logical) to find the points with the distance (eg 10ish mile), using latitude/longitude, see Finding distances based on Latitude and Longitude
3) use the calculated as highlighter
The you can get something like this.
This is a very simple demostration and is attached for your reference.
Regards

I know this isn't exactly what you're after, but you can do a manual radial select. Click on the map and press S (or select Radial from the map options), then click and drag and you get a circle with the radius shown in miles.
Maybe that would help ?

If you have 2018.3 or newer, here is an potion.
Displaying Origin location and destinations in range on same map?

Tim Dines Apr 1, 2019 5:21 AM (in response to Nicole Radish)If you go to my Tableau Public page there is one workbook there. You can find the answers to your quest in that workbook. I have a parameter for selecting the length of the radius and the calculations are there to build the circles. I would give you the link but we cannot go to public from my location.

Jeff Shyu Apr 1, 2019 7:18 AM (in response to Tim Dines)Hi Tim,
I was wondering how you were able to create/set your parameters for your worksheet. I would like to incorporate that into my worksheet for other purposes.
Thank you!
Jeff

Jeff Shyu Apr 1, 2019 7:18 AM (in response to Tim Dines)Hi Tim,
Would I need to change any of the code below if I would like to re-purpose it? We have 35 clinic locations that I would like to mark a radius around them too Thank you!
DEGREES(RADIANS( [Longitude] ) + ATAN2(COS(([Radius Distance])/3959)-SIN(RADIANS( [Latitude] ))*SIN(RADIANS( [Circle Latitude] )), SIN(RADIANS([Degree]))*SIN(([Radius Distance])/3959)*COS(RADIANS( [Latitude] ))) )-90
