## Parallel lines description

Parallel coordinates are a common way of visualizing high-dimensional geometry and analyzing multivariate data. It is a diagram composed by several entities visualized as points along a vertical lines and links between them visualized as wavy lines.
The user is able to interact with the diagram. Basic operations are:

• Highlight families of wavy lines by hovering the mouse in the top part.
• By SQL change the vertical lines order (e.g. swapping two adjacent vertical lines).
• By SQL change the mapping of points along the vertical lines.

The example shown here is based on a data model made of entities and relationships. Each entity is characterized by a number of properties. The relations are just connections or links between entities.
This example visualizes a number of investments extracted from the demo data-set. For each investment we consider these entities:

• The invested amount
• The date of the investment
• The total amount of all the investments made by the investor
• The total amount of all the investments received by the company
• The number of company employees
• The number of articles mentioning the company

By simple SQL query it is possible to extract data from the database and show them directly in the form of a diagram. Each vertical line of the diagram represents a set of same entity, in this way you can compare an arbitrary number of entities type by viewing the connections between the data.

You can see the relations between pair of adjacent vertical lines represented as curved arcs.
