This bar chart example demonstrates how to visualize state-level healthcare data from a CSV file, showing the raw facility counts for each state. Using D3 v5 with SVG rendering, the code loads the data via `d3.csv` and prepares it for display, though the full bar chart rendering is not yet implemented. The example also includes sample city population data and utility modules for colors, showcasing the structure of a VizHub project with ES6 module imports.
