General Usage

I am getting this exception in Pluto while using SankeyPlots.
Although i am getting correct sankey plot.

Failed to guesstimate plot size

exception

Perhaps if you showed the Julia code that generated this error, someone might be able to identify what’s going wrong.

using SankeyPlots
import PlotUtils: palette
src=[1, 1, 4]
dst=[2,3,2]
weights=[2,2,10.8]

It looks like there’s a bug in the way Pluto.jl handles plots created by SankeyPlots.jl.

The error is from this line in Pluto.jl/PlutoRunner.jl.
