We have vast experience in D3JS. We are very interested in this project. I have read your above description and i think its well within our range to execute this is in a good time frame so would you be kind enough to message me so we can have a fast and understanding agreement.
Hi there,
We have reviewed the chart and can do it in D3.js. We have done complex visualization in this lib and can showcase our skills. We've also develop this chart using a Bitcoin lib and we can share the details in chat.
Thank you
