And extending Ali's solution you can actually get the data in to 
a two dimentional array at compile time and have it in static 
memory with a small adjustment:

static immutable matrix = import("data.txt")
     .split("\n")
     .map!(a => a.split(",").map!(to!int).array)
     .array;

void main() {
     writeln(matrix);
}
