Create a Chart/Statistics functionality for my website

I would like to have an easy-to-use charts-functionality for my wordpress website. This is how I want to implement this on my website: 1. The visitor goes to the website and compare two products with eachother (I already have solved this with two search-boxes and a "compare" button). 2. A website like: [login to view URL], will launch (Already solved also). 3. The website will be filled with specifications/values from the excel sheet, values taken from product1 and product 2 only. These will be visual presented in bar charts (see the attached picture of an example of a horisontal gaming chart with values inside the bars). Bar charts will be shown on different specifications and the two products are visually compared. Get in contact with me if you have a great solution to this, the easier it is to use and to implement, the more I will like it. Also if it has some extra functionality that makes it more userfrienly to the visitor, that would be really good!
