6 . what is this?

The Circos table viewer uses the Circos application to turn data tables into chord diagrams.

into circularly composited visualizations like this

Through the settings panel You can control the manner in which your tabular data is parsed, filtered and displayed.

If you are interested in this approach, read Visualizing Tabular Data - Introduction. If you are interested in the details proceed to Visualizing Tabular Data - How to Use Circos to Visualize Tables.

This kind of plot is implemented in Pentaho and d3.js, which calls them chord diagrams. Circos table visualizations have been used to explore global migration (step-by-step tutorial) and inspired mosaic art.

1 . check data format

Before uploading a data file, check the samples gallery to make sure that your data format is compatible.

  • File must be plain text.
  • Data values must be non-negative integers. If all are <1, multiply them by a fixed factor.
  • Data must be space-separated (one or more tab or space, which will be collapsed).
  • No two rows or columns may have the same name.
  • Column and row names must begin with a letter (e.g. 'A', 'A0', 'A-0') and can only contain letters, numbers and _. No punctuation! No double underscores.
  • Maximum number of rows × columns is 50 × 50.
  • If you are using order, size and color rows/columns in combination they must appear in that order.

If you do not adhere to these rules, expect errors.

2a . upload your file

If you are using the size, order or color options below, make sure your input file has the appropriate content (see samples 5-9).

order
size
color

If you'd like to edit the image (e.g. arrange labels, change specific colors, etc) use the SVG file, which is provided in the download link once the image is created.

2b . try random data

Don't have a data file? No problem, try our random data generator. Adjust the settings to change the figure.

3 . wait 10-30 seconds

Some images can take a while to make &mdsah; be patient.

Current load is 0/2. System is available.

4 . privacy

Do not use this tool on confidential or sensitive information (use the offline tableviewer which has a tutorial). All any files you send or are created during the analysis will be deleted 10 minutes after your upload.

5 . updates

27.sep.22 You can now request an access code to visualize larger tables.

16.aug.22 Updated Max row/col logic. Updated logging. Minor cosmetic changes.

9.oct.15 Updated to use Circos 0.68. Added ability to hide first tick and force drawing last tick, which corresponds to segment size.

7.sep.12 Updated to use Circos 0.63. Batch file in batch/ now uses relative paths.

12.mar.12 Updated sample images.

7.mar.12 Fixed cookie bugs. Added image features: segment radius/spacing and segment/tick label color.

14.feb.12 Fixed bugs caused by Mac and DOS line ends.

8.feb.12 Fixed bugs caused by stale cookies.

3.jan.12 More image settings.

6.aug.10 Added colored ribbon caps to indicate identity of distant segment.

28.apr.10 Added quartile ribbon transparency and color options.

27.apr.10 Added ratio layout and verbose option reports.

23.apr.10 Archive added. Site layout updated.

22.apr.10 You can specify row/col color. See Sample 9.

25.mar.10 Ribbons now have transparency. Images are anti-aliased. Web tool now doesn't crash as often.
