D3 D4 Data Visualization

Hi, my name is Matt S Rinc and your project is relatively easy, more or less involving hiding lines either with styles or declaring their widths with 0 (so no line) etc. I work with D3.js in last three years though more with using R and other javascript libraries for some visualizations. D4 documentation was checked and the solution for you is: 1. Adding points to the chart can be done manually to the data structure or read from CSV or XML (preferably JSON) format e.g. text file or parsed with PHP etc. 2. Removing lines (assuming you mean dotted lines between chart stacks) can be done with enumerating all possibly styles for these lines with javascript/D3 and declaring their visibility. There are other ways possible but this is usually only practical for existing functions/libraries if you don't want to modify them internally (and loose modifications with each upgrade etc). Please provide all data you need for the first problem and if I am correct with the second problem. I'll then write and send you your charts. Looking forward to your reply, Matt
