Forked from Selecting a Year on a Line Chart

This interactive line chart displays population estimates by region from 1950 to 2100, sourced from UN population data. Users can hover over the chart to select a specific year, which updates a vertical line marker and re-orders the color-coded legend. The visualization uses d3.scaleTime, d3.scaleLinear, d3.line with curveBasis, d3.nest, and d3.mouse to handle interactions. A color legend built with custom D3 code lists regions using d3.scaleOrdinal and d3.schemeCategory10, while axes and labels are rendered as SVG elements.

Fork of Selecting a Year on a Line Chart

This interactive line chart displays population estimates and projections for world regions from 1950 to 2100. Users can hover over the chart to select a specific year, which draws a vertical black line and updates the selected year used for sorting the color-coded legend. The visualization uses d3.line with curveBasis for smoothed paths, d3.scaleTime and d3.scaleLinear for axes, and a d3.mouse event handler to trigger year selection. Data comes from UN population estimates loaded via d3.csv.

Fork of Selecting a Year on a Line Chart

This interactive line chart displays population estimates and projections for world regions from 1950 to 2100, sourced from UN dataset CSVs. Users hover over the chart to move a vertical line selecting a specific year, which updates the visualization's focus. The d3.v5 code uses scales (`scaleTime`, `scaleLinear`), a line generator with `curveBasis`, and axes, while a custom color legend maps region names via `scaleOrdinal`. The SVG rendering includes blended stroke paths, an interactive mouse-interceptor rectangle, and a responsive update loop triggered by year selection.

Fork of Selecting a Year on a Line Chart

This interactive line chart displays population trends over time by region, with a movable vertical line that updates the selected year on hover. The visualization uses d3.scaleTime, d3.scaleLinear, d3.nest, and d3.line with curveBasis to render smooth paths from UN population estimates and medium-variant projections (1950–2100). A d3.ordinal color scale distinguishes regions via a legend, while mouse events trigger year selection through d3.mouse and axis inversion. SVG rendering handles all elements, including gridlines, labeled axes, and an interactive overlay rect.

Fork of Selecting a Year on a Line Chart

This interactive line chart displays population trends over time by region, using data from UN population estimates. A vertical black line marks the currently selected year, and users can hover over the chart to update this selection, which the visualization updates in real time. The D3 code organizes regions by color using `d3.scaleOrdinal` and `d3.schemeCategory10`, draws the lines with `d3.line` and `d3.curveBasis`, and renders axes with `d3.axisLeft` and `d3.axisBottom`. A custom legend component maps colors to region names, and the data is loaded from CSV files.

Fork of Selecting a Year on a Line Chart

This interactive line chart displays United Nations population projections from 1950 to 2100, with each line representing a world region. Users can hover over the chart to select a year, triggering a vertical marker that updates the display. The visualization uses d3.line with curveBasis, d3.nest for data grouping, and d3.scaleOrdinal with schemeCategory10 for color encoding. A custom d3.scaleTime handles the year axis, while event listeners on a transparent rectangle detect mouse movement to update the selected year and re-render the SVG.

Fork of Selecting a Year on a Line Chart

This interactive line chart displays population trends over time for various world regions, with a vertical line marking a selected year, which users can adjust by moving the mouse across the chart. Using D3 v5, the visualization employs `scaleTime`, `scaleLinear`, and `scaleOrdinal` for scales, `axisBottom` and `axisLeft` for axes, and `line` with `curveBasis` for smooth paths. Data is loaded from UN population estimate CSV files. The SVG rendering updates dynamically through a selection state, and a separate color legend uses `scaleOrdinal` with a category 10 scheme to identify regions.

Fork of Selecting a Year on a Line Chart

This interactive line chart visualizes population changes over time for world regions, with a vertical line marking a user-selected year. Clicking or hovering along the chart updates the selected year, repositioning the line to show the population at that moment. The visualization uses d3.nest and d3.scaleOrdinal to group data by region, d3.line with curveBasis to draw smoothed paths, and d3.axisBottom and d3.axisLeft for labeled axes. Data comes from UN population estimates and projections split across two CSV files, loaded via d3.csv.

Fork of Selecting a Year on a Line Chart

This interactive line chart displays population trends over time by region, with a movable vertical line and circular markers that highlight the selected year across all series. Users click or drag on the chart to change the selection, updating the visualization in real time. The visualization uses the D3 v5 modules `nest`, `scaleTime`, `scaleLinear`, and `scaleOrdinal` to structure and scale the data, while `axisBottom`, `axisLeft`, and `line` handle axes and path generation. Population data comes from UN estimates (1950–2014) and medium-variant projections (2015–2100), rendered as SVG with semi-transparent strokes.
