Chart and image gallery: 30+ free tools for data visualization and analysis

The chart below originally accompanied our story 22 free tools for data visualization and analysis, but I'm continuing to update it as I cover additional tools. Newest additions are toward the table bottom.

Features: You can sort the chart by clicking on any column header once to sort in ascending order and a second time to sort by descending (browser JavaScript required).

Skill levels are represented as numbers from easiest to most difficult to learn and use:

  1. Users who are comfortable with basic spreadsheet tasks
  2. Users who are technically proficient enough not to be frightened off by spending a couple of hours learning a new application
  3. Power users
  4. Users with coding experience or specialized knowledge in a field like GIS or network analysis.     Next page: Screenshots of several tools
