Gantt chart template from vertex42.com is a free Gantt chart template that works with Excel 2003, 2007, 2010, 2013 and 2016 as well as OpenOffice Calc and Google Sheets. You work with this template in the same fashion as you do with any normal Excel spreadsheet. Yes. I remember when I was in business school I had an analytics course where we used excel and an excel add-on to do k-means cluster analysis for market segmentation, which it is commonly used for. Clustering is used in a variety of big data cont On the Excel menu across the top of the spreadsheet, click INSERT, then OTHER CHARTS, and then select a BUBBLE chart. This is shown below – you can click the image to enlarge it. You can also use a SCATTER chart format – but I have found the BUBBLE charts present better in business reports, as you have more formatting and color options.
