We can now run the Python script on the polygon outline of France and then visual-
ize the results using the script plotVector.py that was created in the Sect. 14.2.4 .

14.2.5 X-Y CSV to OGR Format
It is quite common to receive a list of coordinates in a Comma Separated Value (CSV)
file that you would like to use spatially, for visualization and/or for analysis. Many
GIS packages provide this functionality. To demonstrate some other features of the
OGR Python bindings, we will write a program that will read a CSV file containing a
set of coordinates and use theOGRAPI to create either anESRI Shapefile or Spatialite
layer depending on what the user specifies on the command line. In addition, we
