  2. Use google API to query the latitude and longitude of the addresses, given the information of the location (area and address).

  3. Convert latitude and longitude to cartesian coordinates, assuming linearity with small error due to the restricted range.

  4. Use google maps api to keep a white simplified map of Athens.

  5. Create the voronoi diagram using the coordinates of the points.

  6. Superimpose the results of 4,5 on a single image.
