"Summary" => 'This is an interactive live modelling system which can automatically convert simple <b>tab</b> separated triples or JSON-LD into graphical models and flow diagrams using the <a href="https://mermaid-js.github.io/">Mermaid Javascript library</a>. It has been designed to be very simple to use. The tab separated triples can be typed directly into the web-page, but users can also work and prepare data in three (or four columns if applying formatting) of a online spreadsheet and then just copy the relevant columns and paste them directly into the data entry text box.<br/><br/>In general the tools makes use of a simple set of predefined formats for the flow diagrams, taken from the Mermaid library, but a <a href="?example=example_formats">series of additional predefined formats</a> have also be provided and can be defined as a fourth "triple".<br/><br/>The <a href="./">default landing page</a> presents and example set or data, and the generated model, this example demonstrate the functionality provided. As a new user it is recommended that you try editing this data to see how the diagrams are built. Additional examples are also available via the <b>Examples</b> menu option in the upper right.<br/><br/> The system has also be defined to allow models to be shared via automatically generate, and often quite long, URLs. This can be accessed via the <b>Links</b> menu option, as the <b>Bookmark Link</b>. A static image version of any given model can be saved by following the <b>Download Image</b> option and using the tools provide by the <a href="https://mermaid.ink/">Mermaid Ink</a> system. It is also possible to further edit a model using the full options of the Mermaid library using the <a href="https://mermaid-js.github.io/mermaid-live-editor">Mermaid Live Editor</a>, via the <b>Mermaid Editor</b> link.
