The Julia example doesn't work

[seisman]

The following example in the Julia demo notebook doesn't work:

basemap(region=:g, proj=(name=:Otho, center=(220,30)), figsize=8, frame=:g)
grdimage!("@earth_relief_20m", cmap=:geo, shade=true)
coast!(res=:crude, shore=true, area=1000)
plot!("@hotspots.txt", marker=:circle, size="0.2c", markerfacecolor=:red, show=true)

The error messages are:

┌ Warning: Very likely the projection name (Otho) is unknown to me. Expect troubles

Something went wrong when calling the module. GMT error number = 71

@joa-quim Anything wrong?

[joa-quim]

It's a typo in the projection name. Should be Ortho and not Otho

Thanks and fixed.
