This example demonstrates a chart that responds to browser resizing by redrawing its content to match the new window dimensions. It uses a fixed-position div and extracts its client width and height to set the SVG size. The visualization draws two green, semi-transparent lines forming an X across the plot area, with stroke width set to 100. The redraw function is triggered on the window’s resize event. The code relies on d3.select to append an SVG and d3’s selection methods (`selectAll`, `enter`, `merge`, and `attr`) to update line coordinates.
