Perhaps you should try some spelling variations:
"data visualization python computer program" » "data visualization method computer program" (Expand search), "data visualization methods computer program" (Expand search), "data visualization tool computer program" (Expand search), "data visualization python computer programa" (Expand search)
"and applications in teaching project" » "and application in teaching project" (Expand search), "and applications in teaching process" (Expand search), "and applications in teaching subject" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and applications in teaching project\") OR (\"data visualization python computer program\"))~".
• Removing quotes may allow a broader search: (( and applications in teaching project ) OR ( data visualization python computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("and applications in teaching project") OR ("data visualization python computer program"))*.
