There is a new tool that has just been released called RAW which allows users to easily create visualizations from information in a spreadsheet.
I decided to visualize some information from a US State Department report from October 1945 about nationalists in Vietnam. To do this, I created a simple Excel spreadsheet with the names of people and their political affiliations.
I pasted it into RAW.
Then I chose a layout and how I wanted to map it.
And I got my visualization.
