This line chart displays population over time by world region, with each region represented by a colored path and a color legend. The visualization allows selection of a specific year by clicking on the chart, which updates the display accordingly. Built with D3 v6, the chart uses `scaleTime` and `scaleLinear` for axes, `line` with `curveBasis` for smooth paths, and `scaleOrdinal` with `schemeCategory10` for colors. The data comes from UN population estimates, processed by melting wide-format CSV data into tidy rows.

Selecting a Year on a Line Chart

This visualization shows population trends over time for world regions, with a vertical black line marking the currently selected year. Moving the mouse across the chart updates the selected year and repositions the line. The code uses D3 v6 with SVG rendering, employing `scaleTime`, `scaleLinear`, `line` with `curveBasis`, and `axisBottom`/`axisLeft` for axes. Data comes from UN population estimates CSV files, melted into tidy format for visualization. The color legend is built with a custom `colorLegend` function using `scaleOrdinal` and `schemeCategory10`.

Selecting a Year on a Line Chart

This line chart shows population over time for different world regions, with a vertical line marking a selected year. Users can hover over the chart to change the selected year, which adjusts the line's position. The visualization uses D3.js v5 to render SVG elements, including a color legend, axes, and multiple line paths. It also employs D3's scale functions, line generator, and mouse event handling to update the chart dynamically based on the United Nations population dataset.

Selecting a Year on a Line Chart

This visualization displays population trends over time for various world regions using a line chart, rendered with SVG. Users can hover over the chart to select a specific year, which updates a vertical black line to mark that point in time. Built with D3 v5, the code utilizes `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` for axes, `line` with `curveBasis` for the paths, and `nest` to group data by region. The color legend is created using `scaleOrdinal` with `schemeCategory10`. Data comes from UN population estimates.

Selecting a Year on a Line Chart

This interactive line chart displays population over time for different world regions, with a vertical line marking the currently selected year. Users can hover anywhere on the chart to update the selection and the line position. Built with D3 v5, it uses `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis`, plus `nest` for grouping data by region. The visualization renders as SVG and loads UN population estimates from CSV files, using `mouse` events to trigger selection updates.

Selecting a Year on a Line Chart

A line chart shows population over time for world regions, with a movable vertical line for selecting a specific year. Users drag the mouse across the chart, which updates the selected year and redraws the line. The visualization uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `line`, `curveBasis`, `nest`, `axisLeft`, `axisBottom`, and `mouse`. Data comes from two CSV files (UN population estimates and medium variant) parsed with `timeParse`, and the chart renders as SVG with a color legend using `scaleOrdinal`.

Selecting a year on a line chart

This interactive line chart displays population trends over time for major world regions, with a vertical black line highlighting the year 2018 as a selected reference point. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, and `nest` to structure the data, while the `lineChart` function renders the lines with `curveBasis` smoothing. A color legend is generated via a custom `colorLegend` component, and population data comes from UN estimates and medium-variant projections loaded through `csv`. The chart employs SVG rendering with axis ticks and labels styled via CSS.

Selecting a Year on a Line Chart

This example shows a multi-line chart tracking population over time for different world regions, with a vertical black line marking a selected year. Moving the mouse across the chart updates the selected year by inverting the x-scale position, and a color legend identifies each region. The visualization uses d3.line with curveBasis for the smoothed paths, d3.scaleTime and d3.scaleLinear for axes, and d3.nest to group the data by region. Population data comes from UN estimates and medium variant projections, rendered as SVG.

Selecting a Year on a Line Chart

This line chart visualizes population over time for different world regions, from 1950 to 2100, using a dashed vertical line to mark a user-selected year. Hovering over the chart updates the selection, which re-renders the visualization. The code employs D3 v5's `scaleTime`, `scaleLinear`, `scaleOrdinal`, `line`, and `nest` APIs, with SVG rendering. Data is loaded from UN population estimate and medium-variant CSV files, processed via a custom melt function that filters region names.
