Data visualization, transformation of pure text based data to visual presentation, is a very useful technique in communication. With a series of text blocks, readers, especially ones with limited experience on the domain mentioned by the data, will feel hesitate to proceed. It is usually a turn off for human mind to deal with a flood of details at once. Moreover, it is very easy to miss important points when reader tries to skim through those data. Those are the reasons why we should come up with different ways of presenting data. One of that methods is to visualize it in an effective way so that every can learn to read it fast and precisely without missing any points. We have introduced the effectiveness as well as the methodology of diagraming a conversation in the last workshop, which was “dialog – 2 – diagram”. It showed that visualization of a conversation helps to quickly grasp the gist of the story. And from different point of view on the conversation, it is possible to make different diagrams which unveil distinctive perspectives in a conversation. Can we apply these visualization techniques to scenarios other than a simple conversation? The answer is yes, we can. However, different types of scenarios bring different form of data. This variation in data type sometimes results in very complicated visualization. And it, same as a flood of text, becomes a turn off for our mind. One of the most infamous examples of this complication is railways maps, especially the one of Tokyo. There are so many lines with so many different directions. Some lines even share the same track with a slightly difference in time. And in order to encode these difference in a single 2D map, the designer have to come up with a bunch of rules about route coloring and dashing, position approximation, label annotation or legend placement. The designer has to be very careful in setting up the subtle difference between each route, otherwise, it will become a trap for reader to extract any useful information from the map. Besides addressing the making of Tokyo railway maps, our workshop will give a brief introduction about infographics and its applications. We will learn some very simple rules in data classification, color selection, timeline arrangement or perfectly sizing the charts. This will be a great chance for you to read the infographic, create an infographic for yourself and explore the artist side of your brain.
