This line chart shows population growth over time for multiple regions, with a vertical line marking a selected year. Users can move the mouse across the chart to select a different year, which updates the line’s position. The visualization uses D3 v5 to render SVG elements, including axes, line paths with a curve basis, and a color legend. Population data is sourced from UN estimates and medium-variant projections, processed from CSV files. The chart includes interactive mouse events and uses D3’s `scaleTime` and `scaleLinear` for axes.

Selecting a Year on a Line Chart

This interactive line chart visualizes population trends over time by region, with a focus on a selected year. The visualization displays multiple region lines and a movable vertical line; as the user moves the mouse across the chart, the selected year is updated and crosshairs track the cursor. Data is sourced from UN population estimates, and the chart is built with D3 v5, specifically using `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `curveBasis`. The rendering uses SVG and includes a color legend. Interaction is handled via an overlay rectangle’s `mousemove` event, which inverts the D3 scales to update the selection.

Selecting a Year on a Line Chart

This interactive line chart visualizes population trends over time by region, with a vertical black line indicating the currently selected year. Moving the mouse across the chart updates the selected year, repositioning the line and reflecting the change in the visualization. The chart uses d3.scaleTime and d3.scaleLinear to map data, d3.line with curveBasis for the paths, and d3.nest to group data by region. Data comes from UN population estimates and medium variant projections, rendered as an SVG using D3 v5.

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 changes over time for multiple world regions, using a vertical black line to mark a user-selected year. Moving the mouse across the chart updates the selected year, which is reflected in the line’s position. The visualization is built with D3 v5, using `d3.line` for the paths, `d3.axisBottom` and `d3.axisLeft` for axes, and a `mousemove` event listener on a transparent overlay rect to trigger year changes. Data comes from UN population estimates and medium variant projections, rendered as SVG.

Selecting a Year on a Line Chart

This interactive line chart visualizes population trends over time for global regions, with a mouse-driven vertical line denoting the currently selected year. Moving the cursor across the chart dynamically updates the blue selection line, highlighting population values at that moment. The visualization uses D3 v5 with SVG rendering, employing `d3.nest` to group data, `d3.scaleTime` and `d3.scaleLinear` for axes, and a custom `colorLegend` module for categorical color encoding. Data comes from UN population estimates and medium-variant projections, spanning 1950 to 2100.

Selecting a Year on a Line Chart

This visualization displays population trends over time for global regions, with a vertical line marking the currently selected year. Users can hover over the chart to change the selection, which updates the highlighted year. The chart uses D3 v5 with SVG rendering, employing scales like `scaleTime` and `scaleLinear` for axes, and `d3.line` with `curveBasis` for smooth paths. Data comes from UN population estimates and medium variant projections, processed via `d3.csv` and `d3.nest`. A custom color legend shows region names, and the selection uses mouse events to update the year.

Selecting a Year on a Line Chart

This interactive line chart displays population over time by global region, compiled from UN population estimates and medium-variant projections. A vertical line marks the currently selected year, which the viewer can change by moving the mouse over the chart. The visualization uses `d3.line` with basis curves for each region’s series, colored via an ordinal scale. The `mouse` utility captures pointer position to update the selected year, triggering a re-render that redraws the selection line and axis. The SVG is rendered using D3’s selection API, with axes, labels, and a legend generated programmatically.

Selecting a year on a line chart

This visualization shows world population trends over time across regions, with a vertical line marking a selected year. Users can move their mouse across the chart to update the selected year, which highlights the corresponding point in time. The code uses d3.line, d3.scaleTime, d3.scaleLinear, and d3.axisBottom to render the SVG line chart, while d3.mouse captures interactive hover events. Population data comes from UN estimates (1950-2014) and medium variant projections (2015-2100), processed via d3.csv and d3.nest.
