Manual of MDVIS Jigsaw

This is a user guide for the Multidimensional Data Visualization Jigsaw.

Browser requirements: Google Chrome, Safari, Firefox, IE9.

Our system enables users to create, organize and synthesis custom designed visualizations. It helps users work together to analyze the data more efficiently and effectively.

The system consists of two parts: a flexible toolkit to create custom visualizations, and a collection of collaborative tools to help users work together efficiently.

Creating Visualizations

Some fundamental components of multidimensional data visualization are:

  • Axes: Provide coordinates for one dimension.
  • Scatter plots: Draw a scatter plot of two axes.
  • Links: Draw lines between points of two different components.
  • MultiLinks: Draw curves between points of many different components.

Here’s a list of the tools provided in our system.

You can create not only well-known forms of visualizations, like parallel coordinates, scatterplot matrix, but also your own style. With our flexible tools, you are free to create almost anything you want.

Collaboration

After creating your own visualization, you may want to share it to others.

  1. Create an Account & Add Friends:

An account is required to share your visualization. Simply click “Login/Register” button in the top toolbar to register an account. To add friends, click the “Account” button, and input their emails.

  1. Save Visualizations:

After successfully logged in, you can save your visualization. Click the “Save” button above, fill in your comments, then “Submit”.

  1. See others’ Visualizations:

Click “Visualizations” to see saved visualizations. To see others’ visualizations, click the “Load” button to load them into your canvas. You can then modify them to derive another visualization. Also, you can click the “Merge” button to merge their visualization to your canvas.

Correlation Matrix

The correlation matrix in the bottom right corner shows two things:

  • The correlation between each pair of dimensions: See the blue boxes in the upper triangle, the darker the box is, the more related the two dimensions are.
  • How many visualizations about each pair of dimensions: See the gray boxes in the lower triangle, the darker the box is, the more visualizations about the two dimensions.

You may move your cursor on the matrix to examine exact values.

  • C stands for correlation, 1 for functional relationship, 0 for independent.
  • N for nonlinearity, the larger N is, the more non-linear the correlation is.
  • V for the number of visualizations.

Also, you can create a scatter plot by dragging a matrix cell to the canvas.
