+Library that brings interactive [Plotly](https://plot.ly/javascript/) charts to [Swift](https://swift.org/). It is designed to be simple and easy to use thanks to the interface that follows the [Swift API design guidelines](https://swift.org/documentation/api-design-guidelines/).
 
 The design goal is to display an interactive chart of your data as quickly as possible without compromising the more advanced use cases. The intention is to create a plotting tool that can be brought to the rescue in the middle of a debugging session. It is especially helpful to people who work with numeric code, like simulations, data science or machine learning.

Symbol and method names may and generally will change. Before the `1.0.0` release, the recommendation is to depend on `.exact("0.x.y")` version to make_ sure your code doesn't break later.

-## Internals
+# Internals
 
 Internal infrastructure of the library is built on top of [Plotly.js](https://github.com/plotly/plotly.js) and [D3.js](https://d3js.org/) JavaScript packages. Under the hood, Swift instances of chart data, layout and configuration are converted to a serialized JSON representation, packaged and then sent to a browser. Browser is then responsible for rendering of the chart and it also handles user interaction events.
