Visual Analytics allow you to get insight from your data without having to write your own analytic code. This means you're able to get robust, tested analytics working quickly with a minimum amount of effort.
Every site is different - visual analytics allow you to make sure that your analytics are using the correct rules for your particular locations.
The analytics you create aren't just for dashboards - they're available with an API that lets you use those analytic results in reports, spreadsheets, databases or in any tool that can use web content.
Many visual analytics can use a background caching system that means your results are fast, particularly when working with long time-frames.
Many visual analytics have deployment options that let you convert your analytic to a report, a dashboard, create live alerts, and more.
