This example shows a bar chart of student counts by academic program, generated from a small inline dataset of repeated degree names. The code first reads a TSV file conceptually, then uses Lodash’s `_.countBy` to aggregate the raw array by the `c` property, producing a frequency object. The resulting counts are logged to the console and then visualized using Apache ECharts, with the chart container defined as a `div` element. The data is placeholder values, not real file input, and the ECharts configuration is left incomplete.
