This example loads a JSON dataset from a remote URL containing salary information and extracts the “Lower Salary” field from each record for further processing. The visualization uses ECharts 5.3.2 with its stat extension (ecStat) and D3.js v7, which retrieves the data via `d3.json`. The code prepares an ECharts-enabled `<div>` container, though no chart is yet configured, focusing instead on data fetching and console inspection.
