Each dot is a post. Right is more views, up is a higher engagement rate. The lines are the medians, so the four corners are the four kinds of post.

The numbers

It reached 41.6M views, #1 of 1,162 AI chart posts by views, and ranked #256 of 1,162 by score. Among xAI posts it ranked #6 of 23 by score.

The lesson

A scatter plot with 5 models shown drew 41.6M views against a 22.4K median for this type, but 0.010% engagement against a 0.78% median for this type. The form travels far while the engagement rate stays at the bottom.

What it means

At #6 of 23 xAI posts by score, this chart sits below the account's top posts despite #1 of 1,162 by views. The 0.010% engagement rate against a 0.81% median for this account marks the gap between reach and response.
