This interactive bar chart visualizes video game sales counts across different platforms and activities, drawing from a Kaggle dataset. The visualization displays the data as horizontal bars using React with D3 v5, where the y-axis is scaled linearly to represent sales counts and the x-axis uses a band scale for categorical activities. The chart implements custom axis components and marks using SVG rendering, with axis labels formatted through D3's formatting utilities. Users can interact with the dropdown menu to explore different data attributes, while tooltips provide additional context when hovering over individual bars.
