If you take away anything from The Visual Display of Quantitative Information, make it the epilogue. This is the most important part:

Design is choice. The theory of the visual display of quantitative information consists of principles that generate design options and that guide choices among options. The principles should not be applied rigidly or in a peevish spirit; they are not logically or mathematically certain; and it is better to violate any principle than to place graceless or inelegant marks on paper. Most principles of design should be greeted with some skepticism, for word authority can dominate our vision, and we may come to see only through the lenses of word authority rather than with our own eyes.

When we first start out with data graphics, it is easy to read a list of rules about ratios, flourishes, and sizes, and then trick ourselves into believing that is all there is to it. But like cooking, writing, programming, painting, speaking, designing, sporting and numerous other things, you learn the basics first. The principles. And then you figure out what rules can bend and how far.

Not pleased with how the government is handling the budget and deficit? Fine. You fix it. The New York Times provides a budget puzzle:

Today, you’re in charge of the nation’s finances. Some of your options have more short-term savings and some have more long-term savings. When you have closed the budget gaps for both 2015 and 2030, you are done. Make your own plan, then share it online.

Choose wisely.

Lori Montgomery of the The Washington Post reports on the difference between the Democratic and Republican tax plans.

The Republicans’ plan to extend the Bush administration tax cuts for the wealthy would cost $36.6 billion more than the Democrats’ plan, which extends cuts only for families making less than $250,000 a year and individuals making less than $200,000.

As you move down the chart, there are relatively small differences, until you hit the bottom. Medium circle. Huge circle.

This is a guest post by Joan DiMicco, who heads the IBM Visual Communication Lab. Matt McKeon, Karrie Karahalios, and Joan hosted a workshop on Telling Stories with Data. These are the highlights.

What is a story? In a classic sense, a story has characters, events, and a progression. In our postmodern, meta-obsessed culture, we also tend to think about story in terms of the identities of the author and audience.

Now what if the story involves data? How does visualization support telling a story with data? How do journalists think about data visualization as part of their stories? How can visualization tools help data storytellers construct narratives?

Last week I found out that the FDA has a feed for all product recalls and market withdrawals since 2009 and an RSS feed with details. I did a quick search to see if anyone had done anything with the new source of data but didn’t find anything very useful. So to scratch my itch, I banged this out over the weekend.

I’m not entirely sure what we’re looking at here, other than relationships between Mexican drug cartels. Maybe someone can shed some light on the subject.

Wired, in collaboration with Pitch Interactive, has a look at complaints called in over the 311 line in New York. The above is a sample from a week in September, and complaints are plotted by time of day, via the streamgraph approach. As you might expect, there’s a greater proportion of noise complaints at night and early morning, along with lots of road-related complaints during the day.

Inspired by Shan Carter’s simple data converter, appropriately named Mr. Data Converter, Matthew Ericson just put Mr. People online. The tool lets you paste a list of names, and it will parse the first and last name, suffix, title, and other parts for you. You can even have multiple names in a single row.

Years ago, while trying to clean up the names of donors in campaign finance data from the Federal Election Commission, I hacked together a Perl module — loosely based on the Lingua-EN-NameParse module — to standardize names. One port to Ruby later, I’ve finally put together a Web front end for it.

Getting data in the right format, whether for analysis or visualization, can be a huge pain. Imagine. All the data you need is right in front of you, but you can’t do anything with it yet, because as often is the case, it’s not in a nice and pretty rectangular format. So anything that makes this easier and quicker is an instant bookmark for me.

There was a problem on Expedia where a lot of people were choosing their itinerary, entering their information and then dropping off after they clicked on the Buy Now button. It’s like getting to the cash register at a store, and the cashier says they can’t take your money.

So analysts took a look and found that the field to enter your company was confusing people, leading to the input of an incorrect address. “After we realised that we just went onto the site and deleted that field — overnight there was a step function [change], resulting in $12m of profit a year, simply by deleting a field.”

Not bad for a little bit of data digging. I hope the analysts got a bonus.

That said, not every decision has to be driven by data. Balance is good.

People approach data in different ways, especially across different fields. When you’re presented with a dataset that you have to convert to a graphic, what’s the first thing that you do?

For his book The Visual Miscellaneum, David McCandless, along with Lee Byron, had a look at breakups on Facebook, according to status updates. They looked for the phrase “we broke up because” in status updates, and then graphed the frequencies over time. Why they couldn’t just look at updates to relationship status, I’m not sure.

Notice the peak leading up to the holiday season and spring cleaning. Then there’s the people who think it’s a funny April Fool’s joke to say the broke up with their significant other.

Finally, there’s the highlight of Mondays, which you might lead you to believe that people like to call it quits during the beginning of the week. My hunch though is that it happens towards the end of the week, people use the weekend to be sad, and then talk about it on Facebook.

Katy Börner, professor of information science, catalogs visualization and science in Atlas of Science: Visualizing What We Know.

Cartographic maps have guided our explorations for centuries, allowing us to navigate the world. Science maps have the potential to guide our search for knowledge in the same way, helping us navigate, understand, and communicate the dynamic and changing structure of science and technology. Allowing us to visualize scientific results, science maps help us make sense of the avalanche of data generated by scientific research today.

At first glance, without reading anything, it looked a lot like a general scientific visualization book. Sort of like the opposite of Data Flow. Where the visuals lack in aesthetics, they make up for with richness in data and detailed explanations of what you’re looking at. There are a lot of network diagrams, some geographic maps, and a handful of traditional statistical graphics.

All eyes here in the states will be on election results tonight, and all the major graphics desks have been hard at work to provide you up-to-date results as the numbers start to roll in. While you’ll be able to see results just about anywhere you look, here are some of the online spots to keep an eye on. They’ve all got the red, blue, and yellow map, but each provides different functionality.

John Palmer has a look at the past 100 years of government and economic indicators:

This historical perspective visualizes economic trends and spending patterns, during good times and bad. Present-day assumptions regarding core party values have had major shifts over time, and the ridiculous extremes in voter alignment, lobbying, and legislative action are due for revision. As a basis for future shift, this data can educate a presumptive public, empowering citizens to make an informed decision on each and every election day.

I’m not so sure this would help you make a better informed decision as you vote, since the relationship between political party and economy is more complex than true and false. It’s a good historical reference though.

What do you think of the graph overlays on top for GDP, debt, collections and CPI, with different vertical scales?

[Thanks, John]

Every year the Pew Research Center asks Americans what their top political priority is for the year. It should come as no surprise that the economy, jobs, and terrorism top the list.

Jon Bruner for Forbes reports on billionaire contributions to politicians over the past four years:

The billionaires on the Forbes 400 list have given more than $30 million to politicians and political action committees since 2006, along with millions more in soft money to politically active groups. Although Forbes 400 members give about 15% more money to Republicans than Democrats, they fund groups across the political spectrum.

On the top are the billionaires, sized by the amount of donations, and on the bottom are the politicians, sized by amount of contributions received. Click on either or use the drop down menus to see the connections.

It lacks some polish, and I’m not totally sure what measurements are used for vertical and horizontal placement, but worth clicking around.

In what seems to have become an expectation during all major events, a Twitter tracker from the New York Times shows you what candidates are getting the most and least buzz. Each circle represents tweets from a candidate, retweets, and tweets direct at, colored appropriately by party. Press play and they grow and shrink over time. Select a specific candidate(s) to see the specific breakdowns.
