Data Mapper

Data Mapper is a visual planning tool for building and organizing data structures through flowchart-style diagrams.

I originally built it for my own game development workflow. I needed a way to map out how data connects across systems, track relationships clearly, and keep complex logic readable at a glance. What started as a personal tool for designing game data quickly turned into something much more flexible.

Data Mapper lets you visually sketch out how information flows between objects, systems, and ideas. Whether you're planning item data, quest logic, dialogue trees, progression systems, save structures, or other connected data, it gives you a cleaner way to think through complexity before or during implementation.

While it was made with games in mind, it works just as well for other kinds of projects. If you need to organize structured information, map relationships, or build a visual flow of how things connect, Data Mapper can help.

What it's useful for

• Planning game data structures
• Mapping relationships between systems
• Visualizing logic and flow
• Organizing complex project information
• Brainstorming and refining connected ideas

If you like working visually and want a clearer way to design connected data, Data Mapper was built for exactly that.
