Transforming data into insight is critical for projects large and small. Excel has long been used for much of this analysis. But when it comes to visualizing data, creating interactive dashboards, managing unlimited data, and supporting real-time data discovery it doesn’t fit the bill. As Andy Kriebel of Coca-Cola Refreshments puts it, “Excel has its place. I mean, it’s a spreadsheet tool.” But only Tableau turns spreadsheet data into self-service BI. Meet three Tableau aficionados and learn how they’ve replaced what they used to do in Excel with Tableau to discover patterns, expose trends and uncover instant insight from their data.
What is Data Visualizations?
Data visualization is, quite simply, the process of describing information through visual rendering. Humans have used visualizations to explain the world around them for millions of years. Data visualisation allows for universal and immediate insight by tapping into our mind’s powerful visual processing system.
Why is Data Visualisation Important?
Technological advances have made data visualisation more prevalent and powerful than ever before, increasing the importance of business intelligence. Tableau leads the world in making the data visualisation process available to business users of every background and industry. Businesses around the globe realize that the ability to visualize data effectively leads directly to better understanding, insight and better business decisions.
What is Tableau?
Tableau is groundbreaking data visualisation software created by Tableau Software. Tableau connects easily to nearly any data source, be it corporate Data Warehouse, Microsoft Excel or web-based data.
