Visualbox

Visualbox is a simplified edition of LODSPeaKr focused on allowing people to create visualizations using Linked Data.

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 3 questions:

• What is the location of visualbox? If you are running the script in /var/www/visualizations it is highly likely it will be http://localhost/visualizations or http://yourdomainname/visualizations
• What is the domain of the data you want to query? For now, you can leave it as the default (i.e., press Enter)
• What is the URL of your SPARQL endpoint? Where should Visualbox look to execute SPARQL queries.

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
• Alternatively you can run chdmod -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
