Hello & Greetings,
I am a D3.js expert. I have gone through the two links you provided and understood the requirements. I will create a very elegant and efficient interface for you.
Please check some of my recent D3 works:
i) [login to view URL] (Api wrapper on top of d3, with queue support. Tree/Circle packing)
ii) [login to view URL] (Magnetic grid using D3. Can bend edges, do various complex operations using keyboard actions)
iii) [login to view URL] (Dynamically updating area graph. Process JSON data).
iv) An app integrating Google spreadsheet API with D3 charts (no demo because of NDA)
I write robust, clean, efficient and modular code that is easy to maintain and extend. Please check reviews for quality of my work.
Thanks & Looking forward!
JP
