This visualization shows Vancouver’s humidity over time as a single line chart. The SVG line represents humidity percentages across the datetime range, with labeled x and y axes. The code loads data from a CSV file using `d3.csv`, parses timestamps with `d3.timeParse`, and scales the coordinates via `d3.scaleTime` and `d3.scaleLinear`. It renders the line using `d3.line` and displays axes with `d3.axisBottom` and `d3.axisLeft`. The styling applies a steelblue stroke through CSS classes.
