When data is presented in text format, it is generally more difficult to recognize and expose patterns and trends. Data visualization tools and software allow people to present data visually.
Today, data visualization tools go above and beyond the standard charts, graphs, and spreadsheets that were once the hallmark of the field. Data visualization has become sophisticated and multi-faceted, and new but nonetheless visual ways of presenting data have cropped up. Infographics, geographic maps, fever charts, dials and gauges, sparklines, detailed bar and pie charts, and heat maps are all examples of modern data visualization outputs. Some may have an interactive component, allowing users to investigate or manipulate aspects of the image in order to further understand the data behind it. In some cases, indicators are even used to alert users when data has been updated or certain conditions have been upheld. Business intelligence software incorporates data visualization tools into products in order to allow executives to identify major trends in marketing, sales, human resources, operations, or other domains of their business.
