This chart displays a stacked area graph of Slack message volumes over time, with each colored layer representing a distinct data category. The visualization uses the d3.stack() function to aggregate series and d3.area() to generate the SVG path for each layer, colored via a d3.scaleOrdinal() palette. Time values are parsed with d3.timeParse() and mapped using d3.scaleTime(). The data comes from a CSV file hosted on GitHub, loaded with d3.csv().
