I've been using Datawrapper regularly for several months now. One lesson I've learned (with the maps, at least): Even though Substack sort of picks up a post image from the Datawrapper embed, it's better to export a datawrapper map as a PNG image, and then put it in the post Settings as the social media image. This is especially true if the data in the embed is changed; the post image seems not to update.
TIP: Before exporting the PNG, with the maximum map height set to the default of 600px, set the border to about 40px. This puts enough white space around the outside of the image that it will still fit within Substack's 420x300 aspect ratio post image without truncating my titles or footers.
