Build me a d3 dashboard

We want to visualise ski resorts data on a d3 dashboard, which will be publicly available on a website. The dashboard shows all ski locations in Switzerland, is interactive, parametrised, has graphical filters, and dynamic ranking of ski resorts for selected criteria. The data is offline in one big csv file but later will be available on a sql database and daily updated. There is an existing prototype of the dashboard, developed with Tableau, which covers 80% of the requirements. We would like to have better performance in terms of interactivity and filtering, thus seeking a D3 solution. The deliverables are: one D3 dashboard with rendering and reaction time less than 1 second with its commented code as well as a mini documentation of the modules. There is a live prototype: [login to view URL]!/vizhome/20180104_Skiboard/Skiboard
