11:20:52	 From Rosetta Pagliuca : yes
11:20:57	 From Youhana Mikhaiel : Does answering these questions now means that we are no more allowed to submit? Because I haven't submitted yet
11:22:21	 From Rahoui Sara : me too i haven’t submitted yet :o
11:23:06	 From marco.zanetti.12@studenti.unipd.it : Can we see how to properly do the logarithm scale? I found a solution but I don't think is the best one
11:23:31	 From marco.zanetti.12@studenti.unipd.it : ok thanks
11:40:20	 From Hadi Dayekh : It is not too slow thanks for the details
11:46:27	 From pranjita  To  Renaud Blanch(privately) : Professor, I seek a recommendation - is using d3.js the best (and only) option for information visualization? Like do we have any alternative options like using python libraries for the same. Or some internet recommendations also mention  Vue.js or chart.js as easier alternatives to understand than d3.js. I am new to the field of using JavaScript frameworks for visualization and my first course on data visualization just involved using python libraries for it (matplotlib, seaborn, folium and the like) So I ask your opinion about it. Because javascript is not very common usage language for me. But if it is obligatory and we wouldn't have the usability power as d3.js then I would learn it better. 
11:57:51	 From marco.zanetti.12@studenti.unipd.it : If the example get posted can we get some comments on the most "tricky" sections on the code?
11:57:58	 From marco.zanetti.12@studenti.unipd.it : sometime is not as intuitive
12:05:21	 From Junyi ZHONG : “user_id:    +d.user_id,”  can someone help to answer “+” means? i
12:05:42	 From Milena Markovic : That's casting a string to number
12:07:07	 From Junyi ZHONG : Thanks a lot
12:27:17	 From marco.zanetti.12@studenti.unipd.it : yes it shed some light
12:27:53	 From Catarina : yes, about how many people in the groups, so we can start to organize it :)
12:30:09	 From Catarina : how many questions we should do for the next step?
12:30:14	 From Rosetta Pagliuca : How many question should we formulate?
12:30:59	 From Catarina : We should just do the questions or the mapping too?
12:34:13	 From Youhana Mikhaiel : How the project's grade is distributed on these steps?
12:34:49	 From marco.zanetti.12@studenti.unipd.it : Do we have to send mail containing questions and designs?
12:38:13	 From pranjita  To  Renaud Blanch(privately) : Thanks a lot - it answers my question. So while I am free to use other libraries in another language but I will also learn d3 now 
12:38:41	 From Mariana Brejo : the assignements are always to be submited before class on friday?? It is not clear in the webpage
12:43:15	 From Kseniya Shevchuk : please upload this video record somewhere 
12:44:12	 From Youhana Mikhaiel : Can you just please inform us with any major changes in the webpage with email?
12:46:38	 From Iskander : Not everyone is on a good network
12:46:52	 From Marian Aldescu : I won't be able to do that :(
12:47:17	 From Yidong : i dont have a web cam on my desktop
12:47:38	 From Junyi ZHONG : See you , thanks a lot
12:47:40	 From irman faqrizal : see you thank you
