`geom_circle_pattern()`

[Henryjean]

Would love a way to fill in a geom_point with an image of my choice.

Effectively, what I'd like to be to do is re-create a chart like this one:

Each point on the chart would correspond to a different image url in my dataframe, which is then used to fill in the circle.

I can kind of do this with geom_polygon_pattern() but it'd be nice if I didn't have to draw the circle first

Note to self (or future code submitter) - geom_circle from {ggforce} is probably the ideal candidate for adaptation.

Although we'd still welcome a PR that adds a geom_circle_pattern() to {ggpattern} in the future it may be possible to directly use pattern/gradient fills with ggforce::geom_circle(): thomasp85/ggforce#323

• I opened a PR in {ggforce} to allow pattern fills in geom_circle() but I checked and it doesn't really support this use case.
• However I suspect in R 4.2+ (with a compatible graphics device) you could do this in {ggplot2} 3.5+ using geom_point() with shape = 21 (the circle with separate fill) and a large enough size value and a relevant list of grid::pattern() fill values perhaps via gridpattern::patternFill("image").
