A react.js component for modular charting and data visualization. But it seems not so good to me compared to some awesome libraries such as chartjs, plotlyjs, d3js, etc. as it has a limited number of visualizing tools. Although it is easy compared to other libraries, in the battle of feature it will not be a good choice. I recommend you to explore among the above libraries.
Has some nice features (like brush, zoom), but takes a lot of effort to make the charts look decent. Controlling label positioning, width and height was a nightmare.
