My vision of Data and the future
Why Data visualization matters!
I truly belief that Big Data is giving us all a new obstacle to overcome! Information overload is a serious challenge and with Big Data it only multiplies the issue. If you are a data miner you will know that much data has no meaning if you cannot connect any meaningful dots.
Large chunks of data, reports and tables are not effective. It is impressive to get a huge database but it is demotivating for others to read data. The biggest data trend is increasing this issue! Big Data = Information Overload x 10.
From (Digital) Information Age to the (Digital) Understanding Age
A data analyst can analyze data but the most important skill is Data Visualization! These so called "data visualizers" will develop a new skill gathering meaningful information and present it in a very understandable and effective way.
The issue is not anymore the data but the way to give meaning and communicating meaning to others. The person who can do that will have a huge advantage in the so ever growing Big Data world.
Big Data is here! Data Visualizer is on it`s way! In all of my courses I use techniques to create understandable data and present it in an impactful manner.
