I have absolutely no idea why it renders this way on your Chrome, maybe an issue with TypeKit? About the visualization, it was done semi-manually with a tool I've developed to heuristically minimize the crossings, but their is no way to obt

I'll have to go back to my notes, but I'm pretty sure I found a lot of opponents, but maybe I'm remembering wrong. Thank for pointing this out, I'll have another closer look !

Sorry about that, I should have clarified that each Senator could be in different groups, hence the branching. I'll add a little darkness to the background bars. What kind of typesetting issues did you have, and with which version of Chrome

Thanks, the algorithm is a heuristic which optimize a quantity I've called social cohesion ( http://arxiv.org/pdf/1107.3231.pdf ), the article presenting the algorithm itself is currently under review, but basically: first it computes the b

I was not aware of this xkcd comic, funny how things seem to pop out. My inspiration was more in the line of Sankey diagrams. Among others, the famous map of Napoleon's invasion of Russia by Minard ( http://en.wikipedia.org/wiki/File:Minard

Op here, this is part of my PhD research. Please bare in mind that I'm French and that my knowledge of U.S politics is limited to what I can read online. If you find any errors in my analysis or have any tips or other interesting pieces of

Finally, if you’re wondering what’s the best baseline to use, after much dicking about, we’ve discovered that going for something lower (like 11px or 12px) is the best tactic. Whilst this means that most of your elements will be on a d

In my opinion, CoffeeScript is not a language, it's nothing more that an alternative syntax for JavaScript. The argument that one should know CS in order to use a CS library makes no sense, it's nothing more than JavaScript and I cannot str

Because the colors at the end are the one which are closest to the average of all those before. In RYB, the average is what you'd obtain by mixing paints of those colors, so a really earthy tone.

Do you have any reference for that ? (mathematical models of color blindness) ?

by friggeri 15y ago
Not really an encoding problem, I suppose the issue arises because the fallback font does not have those symbols. I can't test on Windows but if someone could point me to a font which has those mathematics characters on Windows I'll gladly

Fixed by removing the generate button, it was totally useless anyway as the update happens directly when you change the number of colors to generate.

It's really, really fast. Congrats ! No accents though: try searching for `é` for example.

Thanks for your feedback ! 1. I didn't want to add too much complexity to the app by going into details of advanced Social Network Analysis, but I'll think about adding details. 2. Good idea, I'll work on a screencast/walkthrough 3. I under

Same thing here, I launched http://whodidiforget.com a few days ago, and after getting a little traffic from HN it fell flat. Sorry for hijacking your post but my question is similar to yours: what to do when you're not on a first name ba

As I said on the other thread, we only use the underlying friends graph for speed reasons: if we had to weigh the edges between people, it would be very costly in terms of API queries, which take time.

I'll rephrase that: adding a weight to an edge is not hard, I actually having several heuristics on hand to do that. It's just really time consuming the first time you do it, because you have to load a lot of data in order to be accurate. M

by friggeri 15y ago
Of course, that's be ideal, but it would take longer to compute the weights. The idea here was really to show that just by looking at friendships it's possible to find accurate results.

Unfortunately, the github repo is private because I can't open source the whole algorithm right now. But I'll definitely do a write up in the next few days.

by friggeri 15y ago
The only information it uses is "who is friends with who". I'm not looking at messages/interactions/networks/existing groups/friends list. Just the underlying graph of friendships.
