Things to do

To-do list for Wikipedia:WikiProject Data Visualization: edit · history · watch · refresh · Updated 2025-06-06

Expand : Adding relevant data graphics to articles if they are useful (see e.g. Category:Health by country and c:Category:Our World in Data)
Update : outdated data graphics that are used in articles (see c:Category:Wikipedia updating and e.g. c:Category:Charts showing data through 2010)
Verify :
- Making sure only data graphics with solid data sourcing are being used (see e.g. c:Help:Misinformation, especially the links to scans in it)
- Making sure data graphics have proper referencing if sourced from elsewhere
Further activities :
- Creating requested data graphics and new data graphics using existing data sources
- Helping each other in creating data graphics (see the Talk page and the resources links below)
- Adding, updating or improving captions of data graphics and polishing how the graphics look like
- Anything related to the m:OWID Gadget
- Possibly various things related to the new Charts extension – see tool graphDataImport and User:GraphBot
- Technical development, bug reporting & ideas relating to data graphics (e.g. issues of OWIDImporter and scripts & extensions like the above)

Resources

Commons:Free media resources/Datagraphics
c:Category:Data graphics, e.g. many charts and maps can be found in c:Category:Our World in Data
c:Category:Interactive data graphics by Our World in Data
Wikipedia:Graphs and charts
Many studies contain data graphics, see c:Commons:Files from studies for information on how to find and upload them
Wikipedia:WikiProject Maps/Conventions
Wikimedia Commons already has many data graphics – see c:Category:Data graphics
PubMed allows exporting results as csv with the "Download CSV" button in the top right for number of studies per year for the query.
Free tools to create data graphics with (e.g. from csv files) include kst, Gnuplot, LabPlot, (add more here)
Wikipedia:Timeline
c:User:RCraig09/Excel to XML for SVG, paste or enter your data into the spreadsheet which can then generate a column of XML code which you can save as an ".svg" file
Commons:Create charts and graphs online
Commons:Convert tables and charts to wiki code or image files
