What is Visualbox?
Visualbox is a "special edition" of LODSPeaKr focused in allowing people to create visualizations using Linked Open Data.
Check out some demos showing what you can do with Visualbox.
Visualbox virtual machine
If you want to try Visualbox but don't want to install it and configure it in your machine, you can download a pre-configured virtual machine ready to be used.Simplest Installation
Simply go to your web server root directory (e.g., /var/www/visualizations) and run
bash < <(curl -sL http://visualbox.org/install)
You will be required to answer 2 questions:
- What is the location of visualbox? If you are running the script in
/var/www/visualizations
it is highly likely it will behttp://localhost/visualizations
orhttp://yourdomainname/visualizations
- What is the URL of your SPARQL endpoint? Where should Visualbox look to execute SPARQL queries (e.g.,
http://dbpedia.org/sparql
.
Finally, give write permissions to the web server in visualbox/meta
, visualbox/cache
, visualbox/settings.inc.php
and visualbox/components
. This can be done in several ways:
sudo chown WEBSERVERUSER visualbox/meta visualbox/cache visualbox/settings.inc.php visualbox/components
- Note You can find the name of your web server user by running
ps aux|egrep "apache|httpd|www" |egrep -v "grep|root"|awk '{print $1}'|uniq
- Note You can find the name of your web server user by running
- Alternatively you can run
chmod -R 777 visualbox/meta visualbox/cache visualbox/settings.inc.php visualbox/components
but this is highly discouraged
Now you can go to http://localhost/visualizations
and you should see the welcome page. You can check now How to create a new visualization
