This is a collaborative assignment. Find yourself a partner. You are welcome to make use of the same partner you are working with for the project.
No milestones to turn in this week, but you should have your data collected (at a minimum) by the end of this week.
This week I would like you to create a visualization that tells us something about the distribution of different supermarkets across the UK. I have gathered together a list of the supermarket locations from the six major chains in the UK (about 3300 stores). I would like a visualization that answers two questions: Which areas of the UK are underserved by the big chains? Are the any of the chains regional (does one dominate a particular area, or is one restricted to a particular area)?
A basic dot density plot is a reasonable start, but difficult to interpret, so I would like you to go one step further. I am leaving the choice up to you. You could use dynamic queries to toggle the different chains on and off. You could use small multiples. You could some up with something else altogether.
To get you started, I have assembled a TopoJSON map of the UK. Note that is also includes Ireland because otherwise Northern Ireland looks funny (your visualization should make it clear that you don’t have data for that region). For help in setting up the projection and getting your map displayed, I suggest reading Let’s Make a Map. It deals specifically with the UK, so pay particular attention to the projection he picks. [Note, however, that you are not using the same TopoJSON file, so the internal names are NOT THE SAME. A very small part of this assignment will be to deconstruct the format to figure out how to use it (I’ll also accept you starting from scratch and building your own TopoJSON file – a step I recommend if you are going to want to work with maps for your final project). ]
The visualization should be contained in a single HTML file called username1+username2_hw7.html (if you need multiple files, you are welcome to make use of a zip file similarly named). Please add appropriate HTML text including your name, date, and the assignment.
I would like this document turned in in the DROPBOX on MiddFiles. You can refer to the reference on the LIS wiki to help you connect to the file server.
