And here's a closer look at that graphic, in case you need it.
I'm trying something new with the puzzle stats this week following an issue that a couple people had with last week's puzzle. Each direction of the coords have their own checksums. Remember, the checksum is the result of adding all the individual digits of the coord. For more information on using puzzle stats see this post.
Please don't spoil the answer in the comments! Hints published tomorrow, and the answer on Wednesday.
