For many years, data users, whether they knew it or not, have struggled with database cardinality issues. I am excited to share a simple solution to this challenge.
How many people died of heart disease last year? Is child obesity on the rise? What’s the biggest health threat Americans face?
The answers to these questions can help save lives by driving improvements in care and prevention. And thanks to open data initiatives, the public has access to the numbers that hold the answers.
But that’s not enough, says Ramon Martinez, a health metrics adviser with the Pan American Health Organization.
With some help from his dad, 9-year-old Ben Radburn visualized the most thrilling roller coasters around the world. The dashboard, which includes a filter for the "drop(est!)” rides, is both impressive and endearing. But it’s only half the story.
How do you know your work is effective? And how can you improve it?
One way is to emulate the 17th century coffeehouse patrons who led the age of Enlightenment.
For social media marketers, the world is full of choices—often too many choices. Which hashtag should I use? When should I post that Facebook update? What’s the best tool for collecting data?
Our social media team is constantly experimenting to see what’s possible with data. Not only do we analyze our own social media channels, we also use social data to explore broader conversations.
Over the past year, we’ve pushed ourselves to ask deeper questions, especially about conversations on Twitter. Using data collected from Tableau partner DataSift, we’ve analyzed World Cup hashtags, SXSW session popularity, and journalists' use of Twitter during the UK general election.
The Tableau community produced a plethora of posts in May, from a commentary on how to approach viz building that provides great time and sanity saving insights, to a detailed comparison of Tableau Server performance on EC2.
What can you do with a simple text-messaging application in Tableau? As one Tableau user put it (in Estonian), the possibilities are endless.
Hundreds of Tableau enthusiasts tuned in for the first European-led Tableau 9.0 Virtual User Group event earlier this month. We showed off the shiny new features of Tableau 9.0, which help data explorers stay in the flow of their work. Psychologist Mihaly Csikzentmihaly calls this flow the secret to happiness, as Tableau’s own Andy Cotgreave explained during his keynote.
In 2013, when I took on a new role as a BI analyst for a nonprofit network of charter schools in Indianapolis, I had no prior experience in business intelligence. Fast-forward to August of 2014: I received a rock in the mail. I’d become a Tableau Zen Master. At first, I thought they had made a mistake and I tried to send the rock back!
Multiple applications hosted on multiple systems usually results in one thing: many separate user accounts each with its own password. For the IT guy responsible for security, this presents a big problem. For one, how do you administer new users and remove old ones, maintain a common security policy, and handle all of those forgotten-email requests?
Having powerful tools can sometimes be a problem. It can encourage us to overcomplicate what should be a simple task.
When finding business value in your data, you should be ready to hold back and remember the KISS acronym: Keep it simple, stupid.
Alberto Cairo first began visualizing data in 1997, when there were few books on the subject. “And obviously we didn’t have social media to connect to each other, or even weblogs,” says Alberto, who teaches data visualization at the University of Miami. Alberto is delighted things have changed since. These days, data explorers have a trove of resources to turn to, including each other. In the spirit of community, he recommends these “little gems”—lesser-known worthy reads for data explorers.
Last week we launched the ability to add a custom logo to your Tableau Online site. This had been a common feature request. Our customers are proud of their brand and want to showcase it when collaborating on data with colleagues and customers.
Last month, I had the pleasure of joining Emily Kund and Matt Francis on their Tableau Wannabe Podcast. I had never been on a podcast and it was such a fun experience!
First responders often say the first and most vital need in a crisis is information. Maps of roads in particular help drive targeted relief efforts. Just hours after the earthquake, volunteers from Tableau joined the Humanitarian OpenStreetMap Team (HOT) to help map Nepal.
