This example shows seasonal trends in live births across Odisha, India, by plotting monthly percentages for total, rural, and urban births from April 2017 to March 2020. Three spline-connected line traces with markers distinguish the categories, and a red dashed horizontal reference line marks a baseline value. The visualization is built with Plotly.js, loading data from a CSV file via `Plotly.d3.csv` and constructing the chart with `Plotly.newPlot`. The x-axis uses date formatting for month and year, while the layout includes a titled legend and custom tick styling.
