Scatter Plot Using Different Data Set
A scatter plot displays tweets per minute across the hours of the day, using time on the x-axis and tweet count on the y-axis. The visualization loads CSV data from a GitHub repository and renders points as SVG circles. D3 v7 APIs such as `scaleTime`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` handle scaling and axes, while `selectAll` and `join` bind data to circles. Tick labels are formatted with `timeFormat` to show hour periods like “AM” and “PM.”
