Tableau Software has just released Tableau Public – a free version of their data visualization tool that will revolutionize how we show information. To showcase its abilities I created the visualization linked below. WARNING: I wanted to push the limits of Tableau – there are 98,000 rows of data shown on the chart, so give it some time to load.
About the data: The NEISS is a database of emergency room visits that involve consumer products collected from 100 hospitals across the country. This is the latest dataset available and covers the entirety of 2008. There were about 370,000 visits in that time frame to these hospitals. As Tableau Public only allows 100,000 rows of data, I used a random function to reduce the dataset.
Using the Visualization: Shown are the 98,000 cases, plotted on the y-axis by age of the patient, and categorized by the type of injury. The lines are colored by body part affected. By default, every product involved is shown. Use the filter on the right to select just a few. For example, deselect “all”, and use the magnifying glass to search for just chain saws, select that product, and allow the chart to update. If you mouse over an individual case, you can see the narrative entered by the hospital about the accident.
The chart provides some information about age spread, and the incidence of a particular type of injury, while still allowing you to look at individual cases. I intend to do a lot more with Tableau and this data set – stay tuned for some dashboards. Click the image to interact with the data.
I’m betting your company has data that you’d like to know more about. Data Driven Consulting specializes in collecting, cleaning, and presenting data just like the example above.
