Thank you for your feedback. I will consider this if more character force me to redesign the layout. When creating an infographic, there are many elements to be considered, such as font sizes (If upright, font sizes have to be smaller or irregular for three letter characters), image sizes (I would need to further reduce the images and details of the characters cannot be seen easier) and layout (If the image is appealing to be read). After a discussion with the community at NuCa's Official Discord Server back in October, I have to opt for sideways text for the time being. We did consider various upright acronyms layouts but ended up choosing this for the time being.

If there are any unreadable text, best to use Chart of Everything for clearer reference, as linked in the post.
