In my last blog post I explored the notion that information visualization is not merely a tool, or art, or an agent of clarity but also has the capacity to generate emotion in users and arguably, become a player in our emotional processing. However, as our information visualization project develops I realize the bigger challenge is not just how to inspire emotion but how to effectively visualize it. Food (one of the variables in our project) is a highly charged, emotive and textured subject and it deserves to be visualized in all its layers and complexity. This lead me to wonder if visualizing emotional content or emotional intensity is perhaps one of the biggest challenges information visualization faces? And have any projects successfully done this?
