Beautiful work, and I do love charts like this since I worked in waterfront operations for a lot of my career.

Since I know you are new here, I have a piece of advice @seadbeady. Use esteem for one post a day. They give a nice upvote and your work is definitely something they would support. We have lot of dapps that would work for you, but this is a good one to start with.

Best of luck on steem. You are just the type of person we need here :)
