I have a set of data points githubdata and I want to draw the smmooth region that they occupy. I want a result similar to what we get when we use RegionPlot. When I ListPlot my data, I get the following image
But I need a smoother image. I want to see the boundary marked by thick lines and smoothed out, just like when we plot something using RegionPlot
Any suggestions on how to achieve this with the given data set?
