Hello.
I'm a JavaScript and HTML5 expert with experience in creating interactive applications with maps, charts, graphs and animations (see my portfolio for examples of my work). I have experience working with various JS libraries (including D3). I require a detailed specification, before I accept a project. All required info can be found in my portfolio. After receiving a specification, or a more detailed description, I can send you screencasts of the work in my portfolio, or other projects. I don't send links of JS projects.
Regards.
