Design an Develop an Interactive, Visualization Based in D3JS - and its a Tree!

We have to design a D3JS based chart that should look like a tree, with its branches, roots, fruits and leafs. You should present your basic proposal of template design at the beginning of this project in order to understand your full capability to reinforce this project. We are not expecting a final design based in real life pictures, but a more conceptual one; search for 'the blog tree'. The tree should be animated, starting to grow once the user lands in the corresponding web page to extent itself according to four different data sets and several complementary rules (thickness of the branches, overall length of the tree, number of leafs per branch, etc.). User will be able to modify the parameters of the data visualisation and the tree should adapt on-line, immediately to this new information. We also expect PDF output For this project its critical to demonstrate experience building D3 templates so please include links and references in your proposal. We are willing to start with a contract project that can evolve to a permanent outsourcing / managed capability model. Many thanks.
