Adding bar chart to product pages

Hello everyone,
I have a very particular requirement, which initially seemed to be doable to me, but considering my web developer couldn’t develop it in last 2 months before abandoning the project, I started looking into problem by myself. But still haven't found anything substantial.
In short statement, my issue is to have dynamic charts (100% stacked bar charts, highlighted till product specification) on the product page, which can show the product specification. (For example for a mobile phone with 2 gb ram, highlighting a chart with min 1 and max 4, till 2 gb).
In long description:
I want to develop an ecommerce website where on product page I can display the specification of products on charts.
For example let’s take mobiles for reference and assume company name as being unique field/tag.
All products have 4 main characteristics. RAM, battery life, Screen resolution and internal memory.
Considering I have all the HTC models information in my data base. Let’s say of all the phones in my database, minimum RAM by any phone is 1 gb and maximum RAM is 4 gb. So my range for RAM is from 1-4. Similarly form Battery its 2000-3500mAh, weight 110g- 220g and internal memory is 8gb- 64gb.
Now what I want is, when user select any product, when the product page comes up, these specification to be shown as four "100% stacked bar charts"
For example, user select a phone of HTC model with following values: 3 gb RAM, 2600mAh battery, 185g weight and 64gb internal memory.
The output I want is 4 charts (one for each specification) with min and max value on left hand and right hand side and then shaded to value of the product specification.
I am wondering, if this is possible or not. It amazes me that adding chart seems so difficult (i have no programming experience, maybe that’s why).
What I have look into, I see there are google charts, highcharts . com, and some other third party players. But still they don’t exactly have solution I am looking for.
Can someone please, advise me, if getting such charts are even possible? Maybe that’s why no ecommerce website has it.
Kind regards,
