I am working in a startup, I need to visualize my data using either a reporting tool or data visualization software (both open source). I need to integrate this tool with traffic data coming from Google Analytics, click-cost data from google adwords and the sales data from a CRM software, what should be the best choice of tool/software I should use to analyze the growth, sales of company and cost effectiveness of ads. I have explored the following options: R programming (in data visualization) and tools such as spagobi, Qlick sense (data reporting tools). Which option I should go ahead with or are there any better alternatives to achieve this goal? Kindly reply ASAP.
Software/Hardware used: R language, Spagobi, qlick sense, D3.js, tableau
