The Geographical area we want to work with today is defined by its lower-left corner [20^oN, 110^{_^o}EW] and its upper-right corner [70^oN, 30^oEW].

Have a look at the subpage documentation to learn how to setup set-up a projection .

The first column is the latitude, the second the longitude, abd and the value of the pressure in in the 6th column.

This information need needs to be given to Magics . This can be done with the mtable data action described in the CSV Input Documentation.

A simple Symbol Plotting using connected line will then give a nice visualisation. The full list of parameters of the msymb object can be found in the Symbol Plotting Documentation.
