Hello Martin, I've noted your question about XFN you sent me.
Yes, those datasets represent connections between websites. Today a common way to list your friends/colleagues/co-residents etc. on your page is to mark up links to their homepages/blogs with an XFN microformat. In a nutshell, this means adding a special `rel="..."` attribute to the `` XHTML tag with a corresponding hyperlink. You may read the following sites to get the idea of XFN and other microformats: 1. gmpg.org/xfn 2. microformats.org To extract XFN links recursively I used XSLT transformations and a Python wrapper script. You can get the sources at sphinx.net.ru/hg/xfn-spider via web interface or Mercurial SCM. Note that while processing the network I also extracted tags marked up with «rel-tag» — another microformat — to generate tag clouds. It's also possible to extract links to RSS feeds for processed sites to generate OPML feed list and import it to your favourite feed reading application. Sounds fun, but XFN-based processing is extremely slow due to network delays. Also, most sites are not well-formed XML so they need to be processed with Tidy before applying XSLT to them =\ |

Sorry for my delay in responding to your question about the Net Spending Introduced by the House of Representatives last cycle--I didn't realize I received a message. I left a comment on the visualization that should explain the disparity. Essentially, freshmen Democrats proposed about a third less spending than returning Democrats. On the Republican side, however, freshmen actually spend more than returners (although the difference is relatively marginal). You can find more data here: http://www.ntu.org/main/press_papers.php?PressID=948&org_name=NTUF

Hi Martin,
I liked the work you did using tag clouds to visualize non-word-related data (ad spending.) I created a color-coded visualization (using XML) to display stock market trends. Font size (7 different sizes) indicate change and color (red, green, or grey) indicate positive, negative or neutral. I think it would be great on Many Eyes to be able to include color on a tag cloud to create a novel visualization (I'm using the term "data cloud") that could combine the accessibility of the tag cloud with the power of a heat map. What do you think? Warren |

>Hi Warren! I saw your message to me about a new kind of tag cloud. Sounds like an interesting idea... Do you have any >examples you can show? >Posted Tuesday August 28, 12:21 AM WarrenA says: Hi Martin, I did a World Population graph on ManyEyes. But I also did a stock market visualization in HTML. There's a screen shot of it at http://en.wikipedia.org/wiki/Image:Top_500_by_volume_on_the_NYSE.png that will give you an idea of what I'm doing. It's more interesting once you do it in java (or embed MouseOvers and links in regular HTML.) The nice part about the stock market visualization is that the names are all (just about) the same size. That avoids the problem in the world population visualization where Bangladesh looks bigger than Pakistan because it has more letters in its name. I'd be interested to know your thoughts on this!

Hi Martin,
I saw your response to my comment on the Scatterplot of chinese population by year and I have one or two other queries and comments: There is a data set from UN Statistics Division, (posted by Jeans) and the key identifies the units of the vertical scale for each plotted variable, but these are in thousands for the unemployment figure, in years for the school life expectancy, and as percentages for the for the adolescent fertility rate, so meaningful comparisons are extremely difficult, if not impossible to make. If the population variable is also selected, only a single bar is distinguishable – since the scale on the vertical axis now stretches to 14,000k (the population is given in thousands, but China has population of around 1.3 billion so the scale should actually be 1,400 k thousands I think. Queries I have relate to search facilities - I wanted to look at data sets or visualisations which had provoked most discussion, but could not see a way to do it - am I missing something?, I would also have liked to see just certain types of graph - for example matrix charts, but could not see how to do that either. best wishes, James Nicholson |

I can't believe I didn't see that. Perhaps I was expecting it to be in text like the other buttons. Thanks for the tip!

Hi Martin,
I wondered if you had any comments about the issues I raised with the chinese population graph and then the scaling and searching facilities in the many eyes software? I know how easy it is for things to slip off the radar, and I would be really interested to hear what you think. best wishes, James |

We Epic Systems together with Beemode (www.beemode.com) have developed a Data Visualisation software almost ready to be released soon.
We are looking for ideas to promote the software. You can view our preliminary version at : www.epicsyst.com/visual.swf Your comments will be appreciated. Hisham Abdel Maguid www.epicsyst.com |

Here is another link for a project we did with Princeton University on US unemployment :
www.epicsyst.com/main3.swf I hope you could evaluate it and give me your comments. So many ideas are there. In a few days you can test the software by uploading data on our website and getting the corresponding Flash charts. This is for a limited number of users. Regards. Eng.

I've used one of your visualizations in a blog post, I don't think I'm required to ask permission but just-in-case. Do let me know if it's a problem and I'll remove it: http://dumbledad.wordpress.com/2008/05/14/transparent-wikipedia-visualization/
