We originally started Pizzacharts with the goal of providing a better user experience for charting Bitcoin prices. Our goal has been to provide beautiful charts for the cryptocurrency community in a way that can communicate as much information as succinctly as possible. As such, we've sweated over each pixel and animation, and provided some features not typically seen on stock charts that can be helpful when charting long term trends or high volatility. For example, our charts can graph the volume logarithmically, invert the chart, chart the volume in either the base or the quote currency, and line knots can be proportional in size to the volume.
Since then, we've packaged our charting as a separate product for developers, which we're now announcing publicly, as we realize it can be useful to the broader financial community.
We aim for our charting library to set a new bar in the charting community as we iterate together!
