Ellen Blackburn

Ellen’s background lies in various Social and Biological Sciences, having recently graduated from Warwick University with an MSc in Biotechnology, Bioprocessing and Business Management, and previously completing a BSc in Criminology and Forensic Investigation.

Throughout her studies, Ellen enjoyed approaching scientific analysis with a creative flair. Accordingly, she revelled in gaining innovative insights from diverse sources of evidence and finding artistic ways to make complex biological concepts more communicable to wider audiences.

Shortly after graduation, Ellen first discovered Tableau through the Data School’s application process and became instantly intrigued by how quickly insights could be gleaned from complex datasets, and the vast creativity the software permitted when conveying analysis.

Aside from data, Ellen enjoys reading, TV, and channelling her creativity into baking.

A Simple Way to Make a Radar Chart

Radar (or spider) charts can be an effective way to show certain types of data. However, they can also make comparison a little difficult; this blog by Graham Odds details why radar charts aren't always the best choice. Nonetheless, I've seen a few on Twitter lately,...

Dashboard Week – Day 4: Getting Custom Maps.

Today we used data concerning the availability of bikes and docking stations from COORD. However, as we were back in 2018.3, the benefits of nice software was balanced out with a bit of a nightmare with trying to get the data (involving an API and an analytic app, see...

Dashboard Week – Day 1: Resorting to a F*cking Word Cloud

On day 1 we were tasked with obtaining data from an API called “F**k of as a Service”, whose descriptor is “a modern, restful, scalable solution to the common problem of telling people to f**k off”. This API will return you an insult based upon the calls you make (see...

Number Formatting: Adding +/- to your values.

When representing numbers in Tableau, particularly when illustrating a change between a category or period, adding preceding +/- signs to your values can make changes more immediately visible. However, this is not a readily available option within number formatting....

Survey Data: Part 2 – Making a Slanted Bar Chart

In Part 1 I showed four ways to represent Likert data, each with varying levels of complexity. Here, I'm going step by step through the most complicated of those views; the slanted bar chart. Within Part 1, I also explained a typical slanted bar chart will often look...

Survey Data: Part 1 – 4 ways to present a Likert scale

Within surveys, a Likert scale allows for standardised and quantitative responses in which answers are scored along a range, often illustrating levels of agreement and disagreement. Survey data can be tricky to make sense of and illustrate. Below are 4 ways in which...

How to make a Pareto Chart

The Pareto principle (or the 80/20 rule) dictates that 80% of the effects come from 20% of the cause. In a typical Pareto chart, values are often represented within a descending bar chart with a cumulative percent of total represented by a concurrent line. An example...

Connecting to Data: Extract or Live?

Extract or Live? Extracts Tableau Data Extracts: (tde or hyper) These are snapshots of data optimised for aggregation. These snapshots are loaded into Tableau’s memory to be quickly recalled/queried for visualisation, accordingly, the database isn’t required to build...

MM34: Conflict in India

This week, Makeover Monday centred around a data set from ACLED which detailed conflict events around the world. Owed to the wealth of data that could be seen spanning across the countries, the various events became difficult to visualise and explore, so I decided to...

The Journey of Anthony Bourdain

Another challenge we underwent last week was our own take on Makeover Monday. Week 33 (a slightly belated post) centred around the travels of the late Anthony Bourdain. After a lot of indecision, I finally came up with this: The next day we presented our work....

TB Take Two

Our challenge for Thursday and Friday was to redo one of our applications to The Data School, by blending it with another data source using Alteryx and creating a new viz on Tableau. I decided to choose my initial application, which explored the global disease burden...

The Alteryx Essentials

Day 2 began with attempting to understand the very basics of Alteryx. Our first day was filled with jokes about how tricky these first few weeks of wrangling new software can be, so we were all expecting a challenge. After a few exercises to help learn the...
