Am I the only one who finds this site undecipherable?

Take this snippet for example:

  American exporters 
  $16.0B of what American exporters sell to Canada sits in headings Canada taxes today, 10.5% of the total. From 8 September it is $26.5B.
  See whose jobs

What does "sits in headings Canada taxes" mean? Whatever this means, how does it jump to $26.5B from $16.0B on a single date? Don't things have to enter for tariffs to be collected?

"See whose jobs" is even more confusing. Nothing about jobs was mentioned. It's talking, presumably about an increase in a tariff collected by Canada. I can understand this will affect certain jobs, but "See whose jobs" just confuses the situation more. I cannot figure out for the life of me what's going on.

Here's another example when you click the "nuclear option" it jumps, without context beyond "Canada’s energy supply is a fourth exposure, and a different kind" to this:

  The nuclear option

  Canada has not done this, and nothing here predicts it will. But tariffs are the smaller lever. Flip the switch to see which states buy their energy from Canada, and whether they have anywhere else to buy it.

  Crude cost per gallon
  $1.86
  what everyone else charges, up 26¢ a gallon

  Both figures are prices the United States actually paid this year: $67.17 a barrel to Canada, $77.92 a barrel to everyone else, across 704 million Canadian barrels. Careful with the gap, though. It is not a pump price, since refining, distribution, tax and margin all sit on top of the crude. Nor is it really a discount: Canadian barrels are mostly heavy crude, and heavy crude sells below lighter grades wherever it goes, so a lot of the difference is just the grade. What replacing one with the other would cost is a question this page does not have the data to answer.

Am I really dumb for not understanding this site, or is this the infogram equivalent of a Nigerian prince email?
