Forked from 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 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 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

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 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 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 line chart displays population trends over time for global regions, using United Nations population estimates from 1950 to 2100. A movable vertical line marks the currently selected year, and moving the mouse across the chart updates the selection to the nearest year, re-rendering the visualization. The chart uses d3.line with curveBasis for smooth paths, d3.scaleTime and d3.scaleLinear for axes, and d3.nest to group data by region. A separate color legend identifies each region, with SVG rendering and d3.mouse handling for interaction.
