Visiting the D3JS homepage and exploring their visualization showcase is my regular leisure hour pleasure, First, it was difficult to bring out that intuition to build meaningful diagrams but spending months fighting that feeling made me good at it, I can build really elegant, attractive and brilliant diagrams using D3JS, I have build diagrams and charts such as Bar, area, pie charts, Sankey, Sunburst, force-directed, heat-map, bubble charts, unit diagrams, chord diagrams and so on
