Diagrams are now much more legible.

Here's what a D2 diagram looks like in 0.2 vs 0.1:

Features 🚀

• double-border keyword implemented. #565
• The Dockerfile now supports rendering PNGs #594
  • There was a minor breaking change as part of this where the default working directory of the Dockerfile is now /home/debian/src instead of /root/src to allow UID remapping with fixuid.
• d2 fmt accepts multiple files to be formatted #718
• font-size works for sql_table and class shapes #769
• You can now use the reserved keywords layers/scenarios/steps to define diagrams with multiple levels of abstractions. #714 Docs to come soon
  • Many other minor compiler bugs were fixed.

Improvements 🧹

• Code snippets use bold and italic font styles as determined by highlighter #710, #741
• Reduces default padding of shapes. #702
• Ensures labels fit inside shapes with shape-specific inner bounding boxes. #702
• dagre container labels changed positions to outside the shape. Many previously obscured container labels are now legible. #788
• Improves package shape dimensions with short height. #702
• Sequence diagrams are rendered more compacted, both vertically and horizontally. #796
• Keeps person shape from becoming too distorted. #702
• Ensures shapes with icons have enough padding for their labels. #702
• --force-appendix flag adds an appendix to SVG outputs with tooltips or links. #761
• d2 themes subcommand to list themes. #760
• sql_table header left-aligned with column #769
• Sequence diagram edge group labels are clearer #782

Bugfixes ⛑️

• Fixes groups overlapping in sequence diagrams when they end in a self loop. #728
• Fixes dimensions of unlabeled squares or circles with only a set width or height. #702
• Fixes scaling of actor shapes in sequence diagrams. #702
• Sequence diagram note ordering was sometimes wrong. #796
• Images can now be set to sizes smaller than 128x128. #702
• Tooltips with ampersand would result in invalid SVGs. #798
• Fixes class height when there are no rows. #756
• Border radius was not firefox-compatible. #799

Breaking changes

• You can no longer use keywords intended for use under style outside and vice versa. e.g. obj.style.shape and obj.double-border are now illegal. The correct usages have always been obj.shape and obj.style.double-border; it just wasn't enforced until now.
