This scatter plot maps the locations of 311 calls reporting human waste in San Francisco’s Mission District, using latitude and longitude coordinates. Each translucent blue circle represents a reported incident, with the plot showing the spatial distribution across the neighborhood. Built with D3 v5, the visualization uses the `scaleLinear` function for the x and y axes, `axisBottom` and `axisLeft` for tick marks, and appends SVG circles. Data comes from a CSV file loaded via the `csv` function, filtered to remove zero-longitude entries.
