Still needs tuning, and the output file is not yet compressed with pngquant (hence the fs-8 name of the current cover), but this is miles better than manually doing Illustrator. I smoothed the dem to prevent spikes and too many contours.
One thing that should be done is make the title more like the Julia logo (space between letters), and maybe move the with to the next line again.
Also, @asinghvi17 liked to add water (polygon) to the the contour plot so one can recognize Prague. I like to add (some of the) coordinates back to indicate a real world location.
