Write some charting software in d3, dimple.js

This project is about a dynamical d3 dimple chart with updates his values on button click. I have already started the project but wasn't able to finish it with my programming skills: [login to view URL],js,output Be aware that is has some bugs. The job is to program a script based on the shown functions in the attached Image ('[login to view URL]'). Basically i need a chart with changes based on dropdown selection and based on value input after the update button click. The chart should then show only the countrys/ continents which are selected and multiplay its base value with the input value. If you have any further questions, feel free to contact me.
