Week 3 at The Data School was the busiest yet! Since my last blog we had presentations at the end of week 2. We each selected a dataset which we then made into a complete visualisation by Friday lunchtime. I selected UK House Prices and restricted my dataset to focus only on areas of London. Surprise, surprise, it turns out… London is expensive. Once I had most of my tableau done, Andy provided some interesting ideas and critique for my viz, including the minimal graph in the right hand corner which tracks how prices have changed in that time period. I really liked this idea, however, it did divide some of the people who felt it needed more explanation or notation. Another suggestion which I thought was useful was to include notable landmarks in my map to make it more accessible to those who are less familiar with London’s geography. Here’s the end viz:
After a long weekend, it was back to Alteryx work! Andre introduced us to the wonderful (and confusing) world of macros.

It was good to begin with a fun and relatively simple dataset before Friday’s bigger challenge, here’s my viz:
Friday morning was the most stressful one so far, we had 3-4 hours to make a visualisation compiling UK Government and Parliament petitions from a certain topic. Here was our checklist:
