This example displays a CSV file of flight data by plotting a position marker on a world map and showing two time-series charts of altitude and speed. The map uses a Natural Earth projection with `d3.geoNaturalEarth1` and `d3.geoPath` to render country boundaries, while the charts use `d3.scaleUtc`, `d3.scaleLinear`, and `d3.line` to draw the data. Hovering over the chart updates the map marker position. Data is loaded via `d3.csv` and vector map data via `d3.json` with `topojson`.
