Hey, I encountered this error too. Check to see if your instance has blocked image hosting recently. Many have been doing so recently due to the CSAM issues on !lemmyshitposting@lemmy.world.

You'll need to host your image on an image hosting site, for example: Imgur or imgbb.

What about a 3D chart, with the 4th axis being portrayed via the Hue value of the point on the chart? That would make it somewhat readable.

I thought every piece in the British Museum was either "missing, stolen or damaged"?

I'm afraid I'm only familiar with the 2-axis political compass: Left/Right and Auth/Lib.

How many axes do you think there should be in an effective political chart, and what aspects of a political position should each one represent?

Sure, for a server as large and accessible as LW, Discord is a super useful, accessible platform. However, the Discord server should not be the only place that such an update is posted.

Realistically, you can't expect much of the LW userbase to see and engage with an announcement in a Discord server, compared to a post on lemmyworld@lemmy.world.
