Charts and graphs are great for simplifying info, showing trends over time, illustrating patterns, and so on. The Commons encourages people to find and create more of them; they should always follow accessibility criteria. Upload them to the Commons, and then put them in the relevant categories. See Category help, and feel free to use category search to find the best categories. Create more categories.

Chart making tools, help, and info on WikipediaEdit

Public domain charts on the webEdit

For public domain templates see list in description: Template:PD-ineligible.

Many charts and graphs are in the public domain because they do not meet the threshold of originality. See the section on charts near the bottom of the article. Shortcuts: COM:TO or COM:TOO. Some examples are the source charts for these Commons charts:

The discussion on whether a chart is in the public domain often concerns the text at the top and bottom of the charts. The safest thing to do is to erase the text, and add your own. This can often make the chart more useful on Wikipedia. You can make the text more legible at smaller chart sizes. You can put the text close to the chart so that the chart better fills out the available space allotted to it in the Wikipedia article. To erase the text see the info in Help:Removing watermarks.

Does a particular chart pass the threshold of originality? Info at links below. Leave your questions on their talk pages.

See Help:Table and the section on the Visual Editor and spreadsheets. Also from Help:Table:

To convert from spreadsheets (such as those produced by Gnumeric, Microsoft Excel, or LibreOffice/OpenOffice.org/ Calc), you can use the Copy & Paste Excel-to-Wiki converter. Or you can save your spreadsheets as .csv and use the csv2wikitable converter.

The online csv2wp script (documentation) converts comma-separated values (CSV) format to wikitable pipe syntax. You may use this to import tables from both spreadsheets and databases (such as MySQL, PostgreSQL, SQLite, FileMaker, Microsoft SQL Server & Access, Oracle, DB2, etc.).
