A bar chart displays worldwide confirmed COVID-19 cases over time, with a tooltip revealing the exact date and case count when hovering over each bar. The visualization uses an SVG rendering with a black-to-orange hover effect, scaling the y-axis linearly and the x-axis with a band scale. It employs d3.v5, the d3.tip library for interactive tooltips, and loads data from a CSV file containing daily global case totals. Axis labels include "Date" and "Number of Confirmed Cases," styled with IBM Plex fonts.
