simple line chart without dataset
A simple bar chart displays an array of sixteen numeric values, rendered as vertical hotpink rectangles with grey outlines. The chart is built with D3 v4, using `d3.select` to create an SVG canvas and `d3.scaleLinear` to map data values to bar heights. Bars are positioned on the x-axis by index, with no dataset file—the numbers are hardcoded in the script. The visualization demonstrates basic D3 bar-chart construction without external data loading.
