Iran’s threats against this Red Sea choke point are a big vulnerability for the oil market
... Oil and product exports through the Bab el-Mandeb nearly doubled to 7.2 million barrels per day in April compared with 3.9 million bpd in February before the U.S. and Israel attacked Iran, according to data provided by Kpler.
The interactive chart by Kpler in the story is a shipwreck.
The data is in millions of barrels per day passing through, as explained in the story. Unfortunately you don't see "million" anywhere in the chart.
What you see is 5.2B, 7.7B, 2.9B, etc., which could easily be misinterpreted as either "barrels" or "billion".
The proper designation should be MMb/d or perhaps MMB/D in the chart, but maybe just leave that out entirely next time because it's already too busy and just put "million" in the subtitle before "barrels" and leave it 5.2, 7.7, 2.9, etc. in the chart.
