With our free XLMiner Data Visualization Add-in for Excel Online, you can quickly visualize data in your Excel spreadsheet, using 8 different types of charts. This Add-in offers a subset of the data visualization features of our Analytic Solver Data Mining product, which also includes advanced data mining and forecasting capabilities.
Both the XLMiner Analysis ToolPak Add-in and the XLMiner Data Visualization Add-in work entirely within your browser on your PC or other device, reading data you select in your Excel workbook, and writing statistical summaries and drawing charts that appear only in your workbook. Once one of these add-ins is downloaded into your browser, it doesn't communicate with other servers. This makes them very "safe" from a privacy perspective.
