i want you to create an html utility users can upload or paste data string we instantly show what visualizations are immedietly available and what visualizations we can transform that data into, the user should be able to click the immediete available and see the visualization and download the implementation code, they must be able to tranform their data (when possible) view and download that new data and use it to generate that visualization view and download the implementation. This is a d3.js chart generator and data manager, we rely heavy on localstorage, this is a full front-end only single-page applications. we will use script type module to utilize es6, our /src code should be meticulously broken down into process folders and the files must be broken down into SRP. any duplicate functionality should be isolated and use factory pattern. do not over-engineer or use defensive programming, plan and validate your plan, then generate the entire app bundled as a downloadable zip
