**2.1 Example 1: Public Transport Use in North America**  The graph below is available online, here: https://plot.ly/~Dreamshot/212 [here](https://plot.ly/~Dreamshot/212)  It is written with a Python script, that you can access by clicking the link (saved here: https://plot.ly/~Dreamshot/213/). in the graph or [here](https://plot.ly/~Dreamshot/213).  Or, see the data by clicking the `data and graph` link. The graph is embedded in an iframe, using this snippet of code that you can use to embed a Plotly graph anywhere: `  seamless="seamless" scrolling="no">`  If you drag your mouse over the data you can see the data points. You can also click and drag to to zoom-in, double-click to zoom-out, and shift-drag to pan. We think this is revolutionary; all in one interface you can access the data, graph, and script used to create a graph, and if you click through, you can save, edit, and copy the script, data, or graph you see below. If we were collaborating on this paper and Plotly graph, we could edit or revise any of this, in real-time. That is collaboration, as it should be.
