Where is a good schematic of Lagrange point 2?

I'm looking for information (free, not paywalled) on the layout of the Lagrange points in Earth's solar system. So far, the best schematic I see is via the mostly free Wolfram Alpha science website:

Evidently, the main limit on the new Webb space telescope's lifespan is its fuel supply: Once its onboard fuel is exhausted (in about 20 yrs), the Webb telescope will drift in space beyond Lagrange 2.
Edit - Here's a short video from Mashable (they borrowed it from NASA) showing the orbit of the JWST spacecraft:

Thank you! Thank you! Thank you!

Thank you LolaWalser. There is also a NASA blog on the JWST, with further explanations I find very helpful:

Attached are NASA descriptors of its Nancy Grace Roman space telescope, scheduled to launch in the mid-2020s and head to the L2 region of our galaxy:

>5 MaureenRoy: "the L2 region of our galaxy:" No doubt this was merely a keyboard slip, but so as not to confuse other readers, I will point out that it is the L2 point of our solar system, not our galaxy.

>6 Foretopman: Hey, thank you for that comment ... right you are.

>7 MaureenRoy: Actually, what I said isn't exactly correct. It's not the L2 point of our solar system, either. It's the L2 point of the Sun-Earth system.

>8 Foretopman: OK. That may be why I got confused about where L2 is, out there. Thank you.
