How to create a flow map

February 2019

Until recently making flow maps has involved manual drawing or knowledge of programming or specialized software. I had learned from my experience developing flow mapping libraries that there was a need for a tool with which people without special knowledge could make flow maps and share them online. This is why I developed flowmap.blue. It’s a web application for publishing interactive flow maps from data uploaded to Google Sheets. It’s free, it requires no installation and allows anyone to create a flow map in no time.
