Read about IBM Graph here.
I was one of four designers who created IBM Graph (along with a large development organization that handled backend development). Our team designed and built Graph's frontend, and helped optimize the user experience of Graph's API.
I plan on doing my own comprehensive write-up on Graph, but in the meantime, I've linked to my coworker Dillon's write-up. I wrote the first draft of the four tutorials highlighted in Dillon's piece, and collaborated with him to build the interactive "Getting Started" experience. Dillon continued to iterate on the interactive tutorials, after I had moved on into a full time Quantitative User Researcher position.
