The Wall Street Journal did a project piece a while back in the “Waste Lands: America’s Forgotten Nuclear Legacy”. They dug through Department of Energy and CDC data to provide an overview of the lingering residue of this toxic time in America’s past (somehow, I have to believe the fracking phenomena of our modern era will end up doing far more damage in the long run).

Being a somewhat interactive piece, I was able to tease out the data source behind it for this week’s challenge. I’m, once again, removing the obvious vis and re-creating a non-interactive version of the WSJ’s main map view (with some additional details).

There’s definitely a story or two here, but I felt that the overall message fell a bit flat the way the WSJ folks told it. Can you find an angle or question that tells a tale in a more compelling fashion? I added some hints in the code snippet below (and in the repo) as to how you might find additional details for each toxic site (and said details are super-scrape-able with rvest). I also noticed some additional external data sets that could be brought in (but I’ll leave that detective work to our contestants).

If you’re up to the task, fork this week’s repo, create a subdirectory for your submission and shoot a PR my way (notifying folks here in the comments about your submission is also encouraged).

Entries accepted up until 2016-04-20 23:59:59 EDT.

Hadley has volunteered a signed book and I think I’ll take him up on the offer for this week’s prize (unless you really want a copy of Data-Driven Security :-).

One last note: I’ve secured 52vis.com and will be getting that configured for next week’s contest. It’ll be a nice showcase site for all the submissions.

#' One teensy discrepancy:
#' ## [1] 517
#' The stacked bars total on the WSJ site is 515.
#' Further complication is that sites$locations is a list column with nested
#' data.frames:
sites <- unnest(sites)
#' ## [1] 549
sum(complete.cases(sites[,c("longitude", "latitude")]))
#' ## [1] 352
#' So, just mapping long/lat is going to miss part of the story. But, I'm just
#' providing a kick-start for folks, so I'll just map long/lat :-)
