This visualization shows global population trends by region over time, with a movable vertical line that selects a specific year to highlight the corresponding values across all displayed series. Users can hover to change the selected year, updating the line’s position via `d3.mouse` and `scale.invert`. The chart renders multiple region lines using `d3.line` and `curveBasis`, with a color legend generated by the custom `colorLegend` module. Data comes from UN population estimates and medium-variant projections, processed with `d3.csv` and `nest`, and drawn as SVG paths.

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 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 line chart displays global population trends for regions from 1950 to 2100, with a movable vertical line that lets the user select a specific year. The chart highlights population values for that chosen year via circles on each regional line, with a color legend identifying each region. Built with D3 v5, the visualization uses `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to render the SVG chart. Data comes from UN population estimates and medium variant projections, loaded via `csv` and processed through `nest` and `melt` functions. Hover interactions are handled by the `mouse` callback on an invisible rectangle.

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 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 displays global population trends across regions from 1950 to 2100, with a vertical marker indicating the currently selected year. Users hover over the chart to update the marker and select a new year. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `nest`, and `line` with `curveBasis`, rendering in SVG. Data comes from UN population estimates and medium-variant projections, processed via CSV loading and a custom melt function.

Selecting a Year on a Line Chart

This line chart displays global population trends by region from 1950 to 2100, with a draggable mouse interaction that updates a selected year to highlight a specific time point. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, and `nest` to organize data, while a custom `lineChart` module renders SVG paths with `d3.line` and `curveBasis`. A brush-like `rect` element captures `mousemove` events to invert the x-scale and trigger year selection. Data comes from UN population estimates, with a color legend built via a reusable `colorLegend` function.

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.
