2.2 Top 5 Stale Issues:
We consider stale issues to be issues that has had no activity within the last 30 days. The team should work together to get these issues resolved and closed as soon as possible.
- Tooltips for emoji in Diagram Syntax doc tree: This issue addresses the lack of explanatory tooltips for emoji used next to diagram type names in the "Diagram Syntax" section of the documentation, which currently leaves users uncertain about the meaning of these icons. The proposal suggests adding tooltips to these emoji to improve user understanding and clarity when navigating Mermaid diagrams.
- log scale for
xychart-beta: This issue proposes adding ascalestring field to thexychart-betacomponent that defaults tolinearbut can also acceptlogas an option, enabling logarithmic scaling of chart data. This enhancement aims to allow users to maintain version control over graph descriptions with original values while displaying the data on a logarithmic scale, with potential for future extension to other scale types. - Unable to Style Sequence Diagram Title: This issue describes a problem where users are unable to change the font size of the title in sequence diagrams created with Mermaid, resulting in titles that appear very small and difficult to read. The reporter notes that while other diagram types in Mermaid support title styling attributes, such as font size, this functionality is not yet available for sequence diagrams, and the current workaround involves using a Markdown title instead.
- SVG rendering formatting issues with markdown input: This issue addresses problems with SVG rendering when nodes contain markdown formatting in diagrams created with Mermaid. Specifically, it highlights that opening the SVG in a new tab causes additional height to be added to the node, while downloading the SVG results in text being cut off without adjusting the node height, leading to formatting inconsistencies.
- Vite build error with mermaid version 10.9.0: This issue describes a problem encountered when building a Vue 3 and Vite application that uses Mermaid version 10.9.0 to render graphs. While the graphs display correctly during development, the build process results in a runtime error related to setting properties on an undefined object, causing the application to fail on startup.
2.3 Open Issues
This section lists, groups, and then summarizes issues that were created within the last week in the repository.
Issues Opened This Week: 5
Summarized Issues:
- SVG Export and Rendering Issues: Several issues highlight problems with SVG output from Mermaid diagrams, including SVG files that cannot be imported into design tools like Figma due to black boxes and lost styling, and incorrect SVG attributes such as a lowercase
viewboxand improperwidthandheightsettings causing rendering failures. These problems make the exported SVGs unusable or visually broken in various environments, impacting user workflows that rely on accurate SVG exports. - issues/6915, issues/6919
- Diagram Rendering Crashes and Export Failures: There are critical stability issues where specific Mermaid diagrams cause crashes in applications like Obsidian and the Mermaid online editor, and rendering failures occur during PDF exports due to errors like
getBoundingClientRectreturning null. These issues disrupt the user experience by causing application crashes or missing diagrams in exported documents, particularly affecting users on macOS with certain Obsidian versions. - issues/6920, issues/6922
- Feature Request for ER Diagram Aggregation Support: There is a request to add support for aggregation in ER diagrams within Mermaid, indicating a need for enhanced diagramming capabilities. This feature would expand the functionality of Mermaid's ER diagrams to better represent complex relationships.
- issues/6909

It emphasizes implementation with capacity building and continuous monitoring to enhance access, retention, learning outcomes, and aspirations.
- issues/6891
- Diagram Node Shape Customization: This issue discusses modifying Mermaid diagram nodes from rectangles to diamonds while keeping the node text intact without repeating it in the syntax. It focuses on improving diagram customization and syntax efficiency.
- issues/6906
- Package Downgrade Regression: This issue reports an unintended downgrade of the "marked" package during the update from Mermaid version 11.10.1 to 11.11.0, likely caused by a regression or merge conflict. It suggests restoring the package to its previously updated version to fix the problem.
