Henry Garner is a graduate from the University of Oxford and an experienced developer, CTO, and coach. He started his technical career at Britain's largest telecoms provider, BT, working with a traditional data warehouse infrastructure. As a part of a small team for 3 years, he built sophisticated data models to derive insight from raw data and use web applications to present the results. These applications were used internally by senior executives and operatives to track both business and systems performance. He then went on to co-found Likely, a social media analytics start-up. As the CTO, he set the technical direction, leading to the introduction of an event-based append-only data pipeline modeled after the Lambda architecture. He adopted Clojure in 2011 and led a hybrid team of programmers and data scientists, building content recommendation engines based on collaborative filtering and clustering techniques. He developed a syllabus and copresented a series of evening classes from Likely's offices for professional developers who wanted to learn Clojure. Henry now works with growing businesses, consulting in both a development and technical leadership capacity. He presents regularly at seminars and Clojure meetups in and around London.

Exploratory data visualization

At the outset of any data science project, there is likely to be a period of iterative data exploration when you gain insight into the data. Throughout this book, Incanter has been our primary visualization tool. Although it includes a large number of charts there will be occasions when it won't contain the ideal chart for the data you seek to represent.

Note

Other Clojure libraries are stepping in to offer exploratory data visualization capabilities. For examples, see clojurewerkz/envision https://github.com/clojurewerkz/envision and Karsten Schmidt's thi-ng/geom at https://github.com/thi-ng/geom/tree/master/geom-viz.

For example, back in Chapter 1, Statistics, we used a scatter plot with alpha transparency to visualize the voter turnout proportion against the proportion of votes for the winner. This wasn't an ideal chart, because we were primarily interested in the density of points in a particular area. Alpha transparency helped reveal the structure of the...

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar? We did, then collated those deliberations into absurd research articles with fake figures and methodologies inspired by even more fictionally absurd studies.
