Re: Visualizing Linked Data - did we miss anything?

Thanks, Alvaro.
In fact EUCLID uses the music domain throughout and there are several MusicBrainz/Beatles examples in Chapter 2, as can be seen here (that's me karate-chopping the air): 
https://vimeo.com/61618438
and in the slides here:
http://www.slideshare.net/EUCLIDproject/querying-linked-data
We're working on re-mapping MusicBrainz to RDF, using R2RML, with more coverage of the Advanced Relationships than has been attempted so far (which is the basis of EUCLID-sponsored tutorials at the forth-coming London SemWeb meetup then at ESWC and SemTechBiz in San Francisco). In case this is useful to you for further examples, please do let us know.

Thanks for pointing that out. My hosting had some problems yesterday, I checked and all the demos are working now.
Re. LODSPeaKr, it is not focused on the music domain, it happens that sometimes I like to use examples from music. In a different domain, http://healthdata.tw.rpi.edu is a portal for health data based on LODSPeaKr. We recently won the first prize in the HealthData Metadata Challenge with it. http://logd.tw.rpi.edu (focused on government data) also uses LODSPeaKr and you can check more demos and applications at http://alangrafu.github.com/lodspeakr/applications.html
Re. the domains used, I'd suggest finding something that is appealing to the community you try to reach. When I present examples for general audiences I try to use well-known examples, like in http://lodspeakr.org/beatles. Last time I presented LODSPeaKr it was to a group of people related to climate and earth science, so I create a demo related to climate change. 

Hope it helps

    Dear Alvaro,

    thank you for the pointers. I was aware of visualRDF and naturally
    Graves but Visualbox (unfortunately the links to the demos are not
    working, for example, http://visualbox.org/demos/cars) and
    LOSPerKr new.

    What I also find really interesting is the LODSPeaKr is focused on
    the music domain, we are currently doing most of our examples in
    that domain as well because the data is quite well aligned and
    there are a lot of dimensions that can be visualised in different
    ways. This will make it also very easy to include as part of the
    content that we are preparing.

    Have you discovered any other domains, which are quite complete
    and easy to visualise (without fixing the data too much)?

    Thanks,
    Maria

    Dear Maria,

    I created a few Open Source tools that may be relevant to the
    EUCLID project:

    - visualRDF (https://github.com/alangrafu/visualRDF) is a tool to
    visualize and explore RDF graphs
    - Visualbox (http://visualbox.org) is a tool to create
    visualizations based on Linked Data via SPARQL queries.
    - LODSPeaKr (http://lodspeakr.org <http://lodspeakr.org/>) is a
    framework to create Linked Data applications

    Let me know if you have any question re. these tools.

    Best,
    Al

        Dear all,

        we are trying to compile a survey of topics and tools for
        visualizing Linked Data. This is part of the contributions of
        the European project EUCLID (http://www.euclid-project.eu
        <http://www.euclid-project.eu/>), which aims to provide an
        educational curriculum for Linked Data practitioners. So far
        we have created training materials on introducing the Linked
        Data principles and application scenarios [1
        <http://www.euclid-project.eu/modules/chapter1>], and on
        querying Linked Data [2
        <http://www.slideshare.net/EUCLIDproject/querying-linked-data>].
        Currently we are working on covering visualization. If you
        are a developer or a user of methods or tools, which are
        relevant and we have missed, please let us know (direct reply
