#SWDchallenge: scatterplot! — storytelling with data
It will be interesting to see both where these two measures agree (high across both would indicate the most effective managers, low across both would be those we need to get some help or manage out) as well as where the measures disagree (scoring high on one but low on the other). A scatterplot is the perfect tool to illustrate this (the scenario is real, but the data in this case is made up):

Re-approaching Color – Lyft Design
For lightness and darkness, there wasn’t a great naming system already in place. We chose to go with a simple scale from 0 to 100, With 0 being the lightest possible color and 100 being the darkest possible color. The only caveat is we needed to be intentional in how we mapped out colors from 0 to 100. If we needed to retroactively add a shade, for example, that could cause us to redo all the numbers and require us to reteach everyone in the organization. So we needed to be correct in how we assigned colors to the scale. We’ll get back to how we did this later on.

By equipping people with those two simple things, hue and brightness names, we had our language. So now if you hear red 60, you’ll know it’s a medium red, and if you see a really light shade of blue, you can guess it’s blue 10. The language is quick to learn and reasonably precise.

Dashboards are becoming one of the most valuable tools for organizations to gain visibility into how they
are performing as well as help develop ways for increasing overall efficiencies. Whether as part of a larger
business intelligence (BI) solution or as a standalone solution, organizations are looking at dashboards to
help solve their business problems. Unfortunately, the ability to sift through solutions and understand the
nuances of the data visualization industry is not always easy. This report aims to provide an overview of
the data visualization market by identifying what dashboards are, the value they provide, what offerings
are provided by vendors, and the considerations organizations should take into account when looking at
To collect this information, a survey of solution providers was performed to identify industry trends, features
and functionality, positioning, etc. Overall, 26 vendors participated in the survey. These include Dundas
Data Visualization, IBM, InetSoft, Information Builders, Klipfolio, PivotLink, Tableau Software, Visual Mining,
and QlikTech. In addition, industry research and interviews were conducted to provide a broad view of the
data visualization industry and the value dashboards provide to the organization. Vendors were broken out
into categories to help identify the types of solutions they provide. These include analytical, operational,
Microsoft specific, and business performance management. In general, vendors fall into multiple categories.
Twenty-eight percent of vendors provide horizontal solutions to their customers letting them customize
dashboards. The most targeted vertical solution is manufacturing at 32%, with high tech a close second
at 28%. Marketing and operations are the most broadly targeted departments within an organization at
44% and 40% respectively. Sales dashboards come in a close third place with 36% of vendors offering sales
dashboard solutions. Business decision makers are the largest targeted market related to decision

storytelling with data
Learning by practice: improving an existing graph sharpens your skills
I'll start with a few comments on the art of undertaking makeovers. Since joining the storytelling with data team last year, I've tackled nearly 100 makeovers of clients' graphs and recently started teaching our custom client workshops. The last section of our workshops is my very favorite: when we turn it over to participants for hands-on practice. We review & discuss their examples of visualizing data and how we might apply the best practices we've covered that day to make the selected examples even stronger. The benefits of hands-on practice are two-fold: participants get feedback on their own visuals AND learn how to thoughtfully critique others' work. For more insight on the feedback process, check out Episode 1 of the SWDpodcast: the art of feedback.

Tableau Love
This month, I was lucky enough to attend the Tableau fanalytics workshop atTC14 and man was it awesome!

The workshop started out with a few words from our MC and Tableau Public Sr. Product Manager Ben Jones who gave us a quick “intro to tableau public” talk and laid out the concept of fanalytics for us. Following Ben’s intro, we were treated to a series of presentations from Tableau Author all-stars; Troy Heerwagen, Kyle Biehle and Carl Allchin, all of whom are data vizzing machines in their own right. These guys are using transportation data, pop culture data, basketball data and a bunch of other hobby based data to create some of the most front page-worthy visualizations around.

Once the presentations wrapped up, we got down and dirty with some data in a group viz building exercise.

The Data Set: Number One Albums from the UK Billboard Charts

The Challenge: Create a viz that showed which albums reached number one and how long they were there.

The Caveat: We only had 15min.

1.1 Billion Taxi Rides on kdb+/q & 4 Xeon Phi CPUs
kdb+/q is considered by its users to have good performance attributes. So this is something I wanted to try for myself, which turned out to give some interesting results. In this blog post I'll see how fast kdb+/q can query 1.1 billion taxi rides. I'll be using the same dataset I've used to benchmark Amazon Athena, BigQuery, Elasticsearch, EMR, MapD, PostgreSQL and Redshift. I've compiled a single-page summary of these benchmarks.
