Earth, moon and JWST. The Moon's orbit is circular-looking but Webb's orbit around L2 is a twisted hoop. The Moon's orbit has a diameter of 477700 miles, whereas Webb's orbit around L2 has a diameter of a bit more than double that, 994000 miles. That's almost as wide as L2 is far from Earth.

Many of the infographics out there are very symbolic, like a subway map; They're not to scale and everything is circles. Webb's orbit around L2 is often shown as similar or smaller than the moon's orbit around Earth. Here is an accurate illustration.
