Chart making tools, help, and info on WikipediaEdit

There is a lot of how-to info, tools, and help on Wikipedia:

Free CC-BY charts on the webEdit

  • Our World in Data. From the about page in the contact section: "If you want to use data or visualizations from the site, you don’t need to contact us: please just go ahead and do so! The terms of our license only require attribution." Use this image license template: {{CC-BY-4.0}}

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. Article shortcuts: COM:TO or COM:TOO. That article has sections on charts and maps near the bottom. There are examples there, and many more examples in Category:PD chart and Category:PD map. For more info see also: en:Threshold of originality.

You can change the text and labels on charts. To erase some text first see the info in Help:Removing watermarks. This is sometimes good to do if there is worry about some text being original enough to be copyrighted. There are freeware image editors such as IrfanView that can edit the text and labels.

Editing the text can also make the chart more useful on Wikipedia. It can make the text larger or more legible at smaller chart sizes. For example; in the thumbnail or medium sizes used on Wikipedia. You can crop the white space around a chart, and put the text close to the chart so that the chart better fills out the available space allotted to it in Wikipedia article.

Does a particular chart pass the threshold of originality? Leave your questions on these 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.).
