Every diagram type.

zombie-mermaid renders 6 Mermaid diagram types, each with a live picker across every one of its 15 built-in themes.

Flowchart

Flowcharts map a process as boxes and arrows and are the most commonly used Mermaid diagram — CI pipelines, decision trees, onboarding steps. zombie-mermaid supports the full shape set (rounded, diamond, stadium, subroutine, cylinder, hexagon, and more), subgraphs, and both straight and curved edges.

State diagram

State diagrams show every state a system can be in and the events that move it between them — useful for anything with a lifecycle: a connection, an order, a UI component. zombie-mermaid supports nested composite states, start/end pseudostates, and animated edge transitions.

Sequence diagram

Sequence diagrams show the order messages pass between participants over time — the standard way to document an API call, an auth handshake, or a distributed-systems trace. zombie-mermaid supports actors, activation boxes, and every Mermaid arrow type.

Class diagram

Class diagrams document a type’s attributes, methods, and visibility in a compact, 3-compartment box — the standard UML notation for object-oriented design docs and API references. zombie-mermaid renders all four visibility markers and inheritance/composition relationships.

ER diagram

Entity-relationship diagrams describe a database schema: entities, their attributes, and the cardinality of the relationships between them. zombie-mermaid renders the full crow’s-foot notation along with PK/FK/UK key badges on typed attributes.

XY chart

XY charts plot bar and line series against a shared axis — the one Mermaid diagram type that’s a data chart rather than a graph of nodes and edges. zombie-mermaid renders both bar and line series, mixed on one chart if needed.
