This example uses Plotly.js to visualize tree data from a CSV file fetched from a GitHub gist. The first chart is a multi-series line chart plotting tree height, diameter, and age against Tree ID, with dashed and dotted lines distinguishing the series. The second chart combines a bar trace showing species counts with a line trace overlaying average height per species. Data is parsed manually from CSV text, and both charts are rendered using `Plotly.newPlot` with custom colors and grid styling.
