We do not care what tool you use. Whatever works for you is fine! Programing, designing, crafting — pick what you prefer or try different things. An extensive list of tools can be found at Visualising Data.
You are free to pick whatever data you want—we do not provide any particular dataset for each challenge. Either use the same dataset for all or different datasets each day, as you like! Search the internet, collect your own, visualize daily experiences or funny stats. Nevertheless, we would like to provide a starter kit of possible data sources:
- Google dataset search
- Data Is Plural
- UN Stats
- OECD Stats
- Socioeconomic Data and Applications Center (NASA)
- TidyTuesday (search through old datasets here, here and here)
- IMDB datasets
- Free GIS data
- WorldClim — maps, graphs, tables, and data of the global climate
- Rdatasets — over 1300 datasets originally distributed in R packages
- List of R packages to import data

- From Data to Viz by Yan Holtz — interactive, with information and codes for each chart type
- DataVizProject by ferdio — interactive with lots of examples
- Visualization Universe by Adioma and Google News Lab
- How to Choose the Right Chart Type — another, very compact, decision tree to help you
