The R, Python And D3.js Graph Galleries by Yan Holtz
The R, Python and D3.js graph galleries are three websites that display more than a thousand chart examples with their reproducible code, using the three main programming languages currently used by developers worldwide.
Each website follows the same organization. The welcome page showcases about 40 chart types ordered by viz category and represented by their icon. For each type, a set of examples is displayed with explanations about the most useful libraries and general code advice. Finally, each example comes with its commented code and can quickly be applied to another real-life dataset.
The galleries should allow anyone to quickly build the chart of their dreams. Beyond technical help, the galleries are also a source of inspiration, leading people to potential new kinds of chart for their dataset. The websites are currently visited about a million times per month, which denotes their usefulness.
