This week’s Makeover Monday took us back to mainland Europe as the dataset challenged me to look at Dutch car purchases. As cars and data go hand-in-hand in terms of my overall interests, this dataset was right up my street in terms of the subject matter.

Working with big datasets is relatively new to me, but I found so many stories with the data that I could tell in my visualisation. But the story that caught my eye was the catalogue price of both hatchbacks and sedans (British for saloons).

I must admit, working with a huge dataset really challenged my ability to generate a simple visualisation, but I am proud of giving the dataset a go for Makeover Monday and trying to produce something with the dataset I had. As I start to become more comfortable with huge datasets, I can start to show what I am capable of in Tableau when generating data visualisations from rows of spreadsheets or from Tableau data extracts.

Whilst this was the viz I did in this first iteration, Neil Richards gave me some feedback on my first attempt. He immediately spotted that my figures did not add up to the charts I was showing on my viz and that’s where I had fallen down. So I did a sense check and made sure that the items I had in my charts did make sense by picking the right models for the cars I wanted.

Here’s the final Makeover I did below by clicking on the picture to get the interactive version of my viz in Tableau Public.
