The Best Diagramming Tool for Visualizing Ideas

I have used Mermaid Chart for years, primarily for sequence diagrams and flowcharts, and I'm starting with C4 Context diagrams. I find it easy to use as a SaaS tool, creating diagrams in clear text. It helps visualize concepts quickly, reducing rework and enhancing shared understanding. I like that it saves as PNG, and I integrate it with Confluence, DevOps, and Word. Its design eliminates distractions, which is beneficial for my ADHD. I wouldn't change anything about it and rate it 10 for recommendation.

Pros:

I have been using Mermaid Chart for years, primarily for sequence diagrams and flowcharts, and recently for C4 Context diagrams. I was introduced to it by a colleague and instantly appreciated how it allowed me to keep documentation updated by modifying a central Mermaid diagram. Setting up Mermaid Chart was a breeze because it is a SaaS tool. It allows me to create diagrams using clear text easily. The tool is fantastic in helping me collaborate with end users to translate their ideas into visual diagrams and then quickly iterate on them. This significantly reduces rework as shared understanding of processes is achieved much sooner. The ability to save diagrams as PNGs is particularly useful, and it integrates well with other software like Confluence, DevOps, and Word. What makes it the best diagramming tool for me is its ability to remove the need to manually position objects on a canvas, which is especially beneficial since I have ADHD and can overly focus on such tasks.

Cons:

Nothing to complain about at all, it has all the features I need, doesn't cost much, never breaks due to new releases

Reasons for choosing Mermaid Chart

Familiarity of Mermaid Chart versus inexperience with Lucid

Pros:

I like how easy and fast it is to create new visualizations. I use it particularly to create Gantt Diagrams and Mindmaps.

Cons:

The Mindmap visualization gets too visually crowded when there are lots of nodes and concepts..

Reasons for switching to Mermaid Chart

The programmable Syntax of Mermaid allows me to create visualizations through LLMs.

Supply chain analyst prefered tool for fast and easy to maintain diagram

I am a 10 YoE supply chain analyst. I used to rely on Microsoft Visio or forms in Excel to map and represent complex diagrams. Since I discovered Mermaid it became my prefered tool for flowchart, supply chain mapping and dataflow.

Pros:

I like Mermaid as it allow me to freely create charts without clicking, draging and resizing on and on and on like on other visualisations tools. I greatly appreciate that both the code and visualisation can be embeded in a Microsoft Teams chat. It never fails to impress my colleagues. I find awesome the ability to work live altogether on a shared diagram.

Cons:

I regret that Value Stream Mapping is not a potential visualisation. It will change the way I do supply chain mapping.

Reasons for switching to Mermaid Chart

Less click and drag. Auto-adjust the flow. Smarter Design. Overall way less maintenance than Vision or making logigram with forms in Excel.
