There are some valid use cases here, I hope this will not affect users of wopr (https://github.com/yaronn/wopr).

curling the markup is not for realtime. sometimes you can get away with curling in a loop with some sleep, and depending on the latency / scale you will get the same effect. however blessed-contrib can also be used as a server side component where clients curl for its endpoint (which is different than curling a static markup). that way it can return a live stream of data. you would use the same approach as https://github.com/yaronn/wopr/blob/master/server/server.js#... where your present method implementation will run in some loop / timeout and keep sending data (by calling screen.render).

To visualize weather in the terminal you can also use:
$> a=$(curl -Ls "bit.ly/1OuRPDJ"); curl --data "$a" "tty.zone?cols=${COLUMNS}"

That's a shortcut for the wopr page

one use case is when ssh-ing machines you can see visual reports rather than text and numbers (think cpu metrics or app specific).

Another example is US weather map:
$> a=$(curl -Ls "bit.ly/1OuRPDJ"); curl --data "$a" "tty.zone?cols=${COLUMNS}"

IMO JSON is less readable for this kind of document. XML is more explicit (at the cost of being chatty) but it's actually good for markup. For example nesting is easier to visually manage with XML due to tooling and explicitness of closing tags.
JSON is good for smaller objects you normally use during coding where you do not want the format to get in your way. Here I actually do want a very explicit format as it's the main thing.

this uses xterm, so it's more accessible to most users than the other alternatives you mentioned. also note wopr is not just about the graphs (like https://github.com/yaronn/blessed-contrib) but also about having a declarative format, and even consuming it with curl.

XML is a standard format for markup (e.g. HTML). When XML is used where it shouldn't (object serialization) it adds complexity. Here it signals that creating a report is as simple (or at least as standard) as creating HTML. What other format you had in mind?
