I need help creating a chart from two columns...

So I have a sheet that has a few unique names in column A and a plethora date+time stamps in column B.

I would like to create a chart which has each of the names on the Y axis and a timeline on the X axis plotting a point where they intersect. I know it's probably obvious but I've been struggling with this for a couple of hours now and I would appreciate any help. thanks!
