Our governments collect vast amounts of data about us and our surroundings. A major part of this data is accessible in the public domain. This data shapes our cities, our villages. It is responsible for policies that affect us. And yet we know so little about it. This data tells stories of times gone by, it is a testament to our history. We can backtrace our paths and see where did we go wrong or better yet, where were we right. A part of why we know so little is because the data does not speak to us nor can we make sense of numbers in tabular formats very easily. It does not come to us in a palatable form. We are visual beings by nature and it is much easier for us to see visuals; may it be a photograph or a graph. Those lines and pixels in two dimensional space tell us of a story that words alone could never describe that well. Visualization of this vast amount of data becomes important in a way that it tells us much more than just numbers could ever tell us. It tells us about the rise and decline of our society, trends and maybe even help us predict what is to come. Maybe it could prevent a disaster or tell us about past ones so that we learn. Before telling of a story of our cities comes the knowing of our cities. Before the visualization comes the data. This project is the first part of the project titled ‘Visualization for Mumbai’s Data’ and focuses on collection and partial analysis of the quantifiable data of the city of Mumbai. The overall project aims to set an example for presenting the data about our cities at large.
