A line chart displays population trends over time for global regions, with an interactive vertical line marking a selected year. Users hover over the chart to update the selection, which shifts the line and highlights the corresponding data point. The visualization uses d3.line, d3.scaleTime, d3.scaleLinear, and d3.nest to group data from UN population estimates, rendered as SVG paths with a color legend.

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 line chart displays population trends over time for global regions, with a draggable vertical line enabling year selection. The chart updates dynamically as users hover, highlighting the selected year across all series. Built with D3 v5, it uses `nest()` for data grouping, `scaleTime` and `scaleLinear` for axes, and `line()` with `curveBasis` for smooth paths. Data comes from UN population estimates (1950-2100), with a color legend and axis labels rendered as SVG elements.

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 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

This visualization shows population trends over time for global regions, with a vertical line marking the currently selected year. Users can move the mouse across the chart to select a different year, updating the line’s position. The line chart uses d3.scaleTime, d3.scaleLinear, d3.line, and d3.curveBasis for rendering, while d3.nest groups data by region. A d3.Ordinal scale with schemeCategory10 colors each line, and a custom colorLegend component displays the categories. Data comes from UN population estimates and medium variant projections, processed with d3.csv and d3.timeParse.

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 interactive line chart visualizes global population trends by region, allowing users to explore temporal changes. A vertical line indicates the currently selected year, and users can move their mouse across the chart to update this selection. The visualization uses D3 v5 to render SVG elements, employing scales, axes, and line generators to plot the data. Population data originates from UN estimates and medium-variant projections covering 1950 to 2100.

Selecting a Year on a Line Chart

This example shows a line chart of population over time for world regions, using a vertical grey line to highlight a selected year (2021). The chart is rendered with SVG, and the code uses d3.scaleTime, d3.scaleLinear, d3.line with curveBasis, and d3.nest to group data by region. A transparent rectangle covers the plot area, and its mousemove event uses d3.mouse and xScale.invert to log the year under the cursor. Data comes from the UN population estimates and medium variant CSV datasets, processed with d3.csv and d3.timeParse.
