Create a interactive graph in d3.js/SVG

Create a plot similar to whats shown in the attachment with d3.js/SVG from three datasets. I have attached the mockup of the graph. Here is what is referred in the graph: 1 is the normal line chart 2 and 3 are timeline graph which means that there is event which has start and end. a is the reference starting point for all the three graphs and b is the reference ending point for all three graphs. The graph has to align with reference to a and b. Please look at the graph before even thinking about bidding the project. The graph needs to be tooltip ready and following things: - There are three graph which aligns exactly. - Create Filters based on columns from the dataset. - The graph has to be interactive which means that the graph when hover over should show tooltip and a line which goes from the top graph all the way to bottom graph. Only bid if you know d3.js/SVG .
