This example plots temperature over time for a week in San Francisco, displaying review_response on the x-axis and temperature on the y-axis. The visualization uses a smooth line generated with d3.line and curveBasis, with scales from scaleTime and scaleLinear to map data values to screen coordinates. The code loads CSV data from a VizHub dataset, parses timestamps and temperatures, and renders axes with gridlines using axisBottom, axisLeft, and tickSize. SVG elements drawn with d3.select and margin-based translation structure the chart.
