This line chart displays Medicaid dental service expenditures over seven time periods, with a red line tracing the spending trend across discrete year intervals. The visualization also includes circular points marking each data value. Built with D3 v7, the `lineT` function generates the path using `d3.line()` with hardcoded x and y scales, while `xPosition` adds the circles. The chart fills the entire browser window and uses hardcoded expenditure values from the dataset.
