Wonderful site. I'm hoping posting small technical questions on this forum is acceptable. If not, please send me on my way (with a destination if you know one).</p> <p>My question. I'm trying to make my first graph in Illustrator and have run into one snag. The graph is a scatter plot with lines drawn between the data points. By default, illustrator represents the data points as small squares. I've been able to change the colour of these squares, but am wondering how (if) I can change their shape (say, from squares to circles). </p> <p>Any and all help is greatly appreciated. I've tried the usual google search, but have had limited success probably because I'm still learning the terminology used by Illustrator. What does illustrator call these little squares?</p> <p>Thanks,<br /> Donovan </p> http://forums.flowingdata.com/topic/visualizing-large-social-network-graph-data#post-2450 Mon, 26 Dec 2011 23:07:24 +0000 firesofmay 2450@http://forums.flowingdata.com/ <p>Hi,<br /> I am looking to create a large Social Networking Graph using the data I have scraped using Python from facebook.</p> <p>What I am interested in is, to Show the interconnections between people, and the nodes should be clickable, and when you hover over the nodes, it highlights the direct connections of them.</p> <p>The data set I am playing with is quite Large, Million Nodes give and Take.</p> <p>I have found static ways to generate the data, but I am looking for is more of interactive view of it.</p> <p>Can anyone suggest me the best to do this?</p> <p>Thanks a lot.

However, although new high-throughput DNA sequencing techniques have opened the door for routinely identifying genome variations that might contribute to a given disease, there are still several bottlenecks that stand in the way of widespread application in the clinic. Several of these issues can be (partly) solved with data visualization techniques.</p> <p>Geneticists rely heavily on genome browsers to investigate genetic variation in their genomic context (see e.g. <a href="http://www.ensembl.org" rel="nofollow">http://www.ensembl.org</a> and <a href="http://genome.ucsc.edu" rel="nofollow">http://genome.ucsc.edu</a>; visualization expert Ben Fry created <a href="http://bit.ly/lBK6wR)" rel="nofollow">http://bit.ly/lBK6wR)</a>. Although of priceless use, these browsers all have the significant drawback that they can only display data relative to a so-called "reference". It is also impossible for them to show rearranged chromosomes as they appear in for example cancer.</p> <p><strong>Aim</strong></p> <p>Within this project, we will build a <strong>new interactive genome browser</strong> that is capable of displaying so-called structural genomic variation and is able to display patient data relative to actual control (healthy) data rather than a theoretical reference.<br /> This visualization will include several features. First of all, it will be possible to visualize the differences in chromosome structure between individuals. This will be based on a directed graph, and might be inspired by the ABySS-Explorer tool by Nielsen et al (<a href="http://bit.ly/iZhLi1)" rel="nofollow">http://bit.ly/iZhLi1)</a>. Secondly, the tool will enable any path through this graph to be considered as the "reference", so that depictions resembling the genome browsers such as <a href="http://bit.ly/l6W0dV" rel="nofollow">http://bit.ly/l6W0dV</a> can be created. Thirdly, it will be possible to simultaneously look at high resolution while still maintaining the context of the whole chromosome. Finally, this tool will be able to visualize different levels of uncertainty in the data.</p> <p><strong>Profile</strong></p> <p>The ideal candidate for this position holds a MSc or PhD degree related to data visualization. He/she should be eager to learn about genomics and variation in the human genome. He/she will collaborate with PhD students and postdocs both at ESAT and the University Hospital in Leuven, as well as with clinical geneticists and international collaborators. The position requires good analytical skills and knowledge of programming languages such as java, ruby or perl. Knowledge of data visualization frameworks such as Processing (<a href="http://www.processing.org" rel="nofollow">http://www.processing.org</a>) and/or Protovis (<a href="http://vis.stanford.edu/protovis/" rel="nofollow">http://vis.stanford.edu/protovis/</a>) are a significant plus. The position should be filled as soon as possible.</p> <p>We offer a competitive package and a fun, dynamic environment connected to a top-notch consortium of young leading scientists in human genetics and cancer. The University of Leuven is one of Europe's leading research universities, with English as the working language for research. Leuven is one of Europe's most beautiful university towns, just outside Brussels, at the heart of Europe.</p> <p>To apply for this position, please send your CV together with a photograph and - if possible - some examples of your work to Prof Jan Aerts (jan.aerts@esat.kuleuven.be).

I use "relative probability diagrams" which are similar to weighted histograms that show the abundances of populations of ages of minerals within a certain rock.</p> <p>Data: I analyze 100 grains, that range in age from say 200 million years to 60 million years. there might be 80 grains that are 70 +/- 5 million, then another smaller group of ages at 100 +/- 5 million years. etc. Each age has it's own uncertainty, so the data are weighted based on abundance and uncertainty. The area under each curve is equal. </p> <p>The curves themselves are fine, but it is cumbersome to display and compare multiple samples because of the height of the curves. I thought about some kind of stacked area chart, but maybe someone else has a better idea.</p> <p>The first image shows the output from the program.</p> <p><a href='http://img23.imageshack.us/i/plot1.jpg/' rel="nofollow"><img src='http://img23.imageshack.us/img23/8061/plot1.jpg' /></a></p> <p>The second image is when I extracted the curves and put them on a common axis, I may have also reduced the vertical scale by 50%.</p> <p><a href='http://img176.imageshack.us/i/plot2.jpg/' rel="nofollow"><img src='http://img176.imageshack.us/img176/9194/plot2.jpg' /></a></p> <p>Anything else come to mind that would help easily compare the main peaks on these curves between samples?</p> <p>If images don't load I will post them in a reply, as there is no preview post option.<br /> Thanks! </p> http://forums.flowingdata.com/topic/social-network-mapping#post-1925 Tue, 05 Oct 2010 12:45:03 +0000 Henky 1925@http://forums.flowingdata.com/ <p>Hey everyone!</p> <p>My name is Henk.

Below is a description. I know R.</p> <p>I have data on peacekeeping operations and civil wars since 1985. "Peacekeeping operations" (PKO) variable takes on 4 values: No operation, UN operation, non-UN operation, mixed operation. I know the value of this variable for each country and each year. I want to show, for the countries that had at least one civil war (around 40 countries), the values of the PKO variable. </p> <p>I imagine a graph where countries are on the y-axis and years are on the x-axis. Each country has a horizontal strip and the strip can each year take a different color depending on the value of the PKO variable (white if "no op", blue if "UN op", yellow if "non-UN op", green if "mixed op"). </p> <p>Could you tell me the name of such graphs and do you know if I can do this in R? </p> <p>Thanks for your help. </p> http://forums.flowingdata.com/topic/diseasome-explore-the-human-disease-network#post-817 Wed, 08 Jul 2009 10:29:00 +0000 seb 817@http://forums.flowingdata.com/ <p>Gephi team presents a science-mapping project: <a href="http://diseasome.eu/" rel="nofollow">Diseasome</a>.
