These are some examples:
Reason for this creating this tool? Since 2025, saw that AIs increasingly used the Mermaid syntax to render charts- first with some errors, but gradually improving.
Hence, studied the syntax and designed a tool. Eventually, saw that most of the diagrams that I used as concepts in my own consulting activities in the past were not available:
- _ waterfall, mainly in financial contexts
- _ bubble charts, mainly to prioritize
- _ along with others (radar, sankey, treemap, Ishikawa, Venn etc)
Eventually, all within the last line above became available (albeit in some cases still as beta or even undocumented), but on waterfall and bubble chart read a lot of talk, little walk.
Added also three other charts useful in change management and planning but not yet available within the standard: heatmap, organizational chart, earned value analysis.
This tool includes in the menu also three underused but, in my view, useful charts for change activities that are already within the standard: radar chart, Venn diagram, sankey (decomposition), Ishikawa ("fishbone")- the latter is already within the standard, but still undocumented on the presentation website, only available in the "technical" website.
You can generated multiple variants of the waterfall and bubblechart- see examples in the first pulldown menu option, and also in the other sections.
To generate your own charts, modify the instructions of an existing example, or copy-and-paste your own.
The menu of this tool contains:
- _ New Proposed Mermaid Charts (an example for each one of the new charts proposed)
- _ Financial Structuring (6 different waterfall examples, plus under "decomposition" a sankey)
- _ Portfolio / Prioritization (a Venn diagram for "pain points identification", a radar chart for "status vs. target", 6 different bubble chart examples)
- _ Strategic Planning & Performance (heat map, organizational chart, earned value analysis)
- _ Causality (5 different Ishikawa examples, to represent both root cause analysis and components of change initiatives)
Please refer to this article within the Organizational Support section for more information on how developed this tool, its rationale, and evolution.
A quick note: I am currently hosting my tool on this website- if the traffic will become excessive, will shift it elsewhere, and will leave here just the link.
And if you ask: yes, as you will see in that article, actually you can just copy-and-paste your own Mermaid syntax, and will render what is supported by the version I developed it for, 11.13.0.
