Webform questionnaire with scoring and reports
If you want to create charts from the survey results of the Webform module, there are 2 typical/popular alternatives to pick from:


Webform Charts (used in about 400 sites), to display Webform results in a graphical manner using a charting library.
Webform Chart (used in about 220 sites), which integrates with the "Analysis" tab of a Webform (created with the Webform module) to provide charts for each individual component's analytical data.


The Drupal 7 version of both modules, requires the Charts module (dependency).
