                            <p> Hello, World! It has been a pleasure and a great ride for doing this. Believe it or not, this is my first project ever using Javascript, HTML, D3, jQuery, Bootstrap or CSS. It took me about 20 part-time days from not knowing
                                anything related to the web to this, plus about a week or two for refinements, tooltips and the overall layout.
                            </p>
                            <p>
                                I wouldn’t be able to do this if it weren't for edX. All the more than 20 MOOCs I participated and 14 certificates I earned were essential here. From Entrepreneurship (<em>who is my costumer? Who is going to see this visualisation?</em>), to Analytics Edge (<em>can I extract
                                anything else from this data?</em>) to even CS50, which I never completed, but otherwise I wound't be able to learn so fast other languages and libraries.
                            </p>
                            <p>
                                I'm extremely grateful and this is my gratitude. Hope it serves as an inspiration. Always keep in mind that, currently, only the first tab, without the blue bars, is everything that is available to the student. Only 14% of edX users access via mobile, but nevertheless this project should work well in any screen. This is the main reason for the tabs above - they are extremely memory efficient.
                            </p>
                            <p>
                                I tried to do my best, focusing in the user and in simplicity, and I am very happy with the result. </p>
                            <p>
                                Hope you also enjoy,
