VegaLite not formatting correctly

I have plotted this graph using VegaLite, but the bars are bleeding over and obscuring everything.

My code:

answer |> @vlplot(mark = {type= :bar}, x = {field = :Overall_mean, scale = {domain = [76,85]}, axis = {title = "Overall Average"}}, y = {field = :Experience, sort = false}, height = 500, width = 500, color = :Experience)
