Hallo,
i'm kind of a newbie to processing, so please excuse me, if my problem is a little too under-your-average problem. ;)
i am trying to program a tool that displays the broadening of a disease on a map. therefor i got a textfile that has

-the index number of the city
-its latitude/longitude
-the index numbers of the cities the city is connected to

so, how am i getting these numbers as variables into my program? with "loadStrings"?
well, but how can i use the data for displaying a rectangle at the coordinates? and what structure should the textfile have?

save the file as tab-delimited text, then use something like this (not tested):

Code:

String lines[] = loadStrings("stuff.txt");
int count = 0;
int index[] = new int[lines.length];
float lat[] = new float[lines.length];
float lon[] = new float[lines.length];
int connected[][] = new String[lines.length][];

for (int i = 0; i < lines.length; i++) {
  String pieces[] = split(lines[i], '\t');
  index[count] = toInt(pieces[0]);
  lat[count] = toFloat(pieces[1]);
  lon[count] = toFloat(pieces[2]);

  // assuming that this column is separated by commas
  // and maybe additional space
  connected[count] = toInt(split(pieces[3]), ",");

  count++;
}
