The graphic is dumb. Stats are given in flow rate, but the moving dots indicate flow rate correlates with velocity, which is just not true.

Does it?
I mean, flow does have a major portion to do with velocity, it’s just that velocity is dependent upon cross sectional area as well.

Right, but as stated earlier in the thread, the Amazon is incredibly wide, and average velocities are at least comparable (1 to 3 fps). The flow rate disparity is what's really being discussed and is where the Amazon is an order of magnitude greater.

speed of flow
There is flow rate (volume / time)
and there is speed (distance / time)
There is no flow speed

Yep. The limits of that watershed are AMAZING.
A few years ago, I visited Emlenton, PA, a small town on the Allegheny River in western Pennsylvania where my paw-paw was born in 1905.
As I ate my lunch at a riverside park, I thought how all the water I saw was going to go within a few miles from my home in Louisiana.
A few weeks ago, I was in downtown Denver at Confluence Park (where Cherry Creek joins the Platte River), and I realized the same thing-- all of the water I saw was starting on a long journey all the way down to where I lived.

There are no bridges across the Amazon River.

Google is telling me the Amazon River is 7 miles wide at its widest.
Not 50 for most of its run
Still hard to wrap your head around, but much more realistic.

The Missouri River is longer than the Mississippi River is from their junction near St Louis. The whole system should have been named the Missouri River.
I believe it would more appropriately be the Ohio, which contributes the lions share of the flow.

Speed varies greatly from portion to portion and by season... but based on averages that I've read, the Nile is faster than the Mississippi which is faster than the Amazon.

True. Most of the Amazon is in dense rainforest, but if there's one thing humans love to do, it's to find some way to defeat natural barriers. We just can't resist doing it. Climb a mountain reaching 5.5 miles above sea level? No problem. Send James Cameron to the bottom of the ocean so he can find out what's behind the door? Done it. Space? shite, we do that every few days now that Elon's on the task. Our DNA almost demands that we build bridges across water.
It's just remarkable that in the entire run of the Amazon we, as a species, have collectively said "Nah, frick that."

Same rock from an ancient eroded mountain range. What you see on both sides now is an eroded mountain from different thrusting events. So technically they are not the same mountains. Similar to the mountains in Arizona are from the ancient Rocky Mountains, and not the same thrusting event the Denver Rockies are.

I've got a thrusting event for you.
