This fork of a "HAW: Birthday data viz" example presents daily birth counts across several years as a monthly line chart. A color-coded year selector lets the user switch between datasets, each rendered as a distinct colored line with a matching gradient area beneath it. The visualization is built with React for state and UI, while D3 v7 (via `csv`, `scaleTime`, `scaleLinear`, `line`, `axisBottom`, and `axisLeft`) handles data parsing and chart rendering. The code loads German-format dates from a CSV file, computes day-of-year values, and displays the time series on an SVG canvas with a dark theme.

#HAW: Birthday data viz

This dashboard displays daily live births in Germany from 2020 to 2024, plotting 1,826 data points as a line chart with clickable and hoverable circles. The visualization uses React for state management and D3.js's `scaleTime`, `scaleLinear`, `line`, `axisBottom`, and `axisLeft` to render the time series. A tooltip shows the date and birth count on hover, while selected points are highlighted in red.

#HAW: Birthday data viz

This visualization displays average weekly birth counts for multiple years as circular, animated dot plots. Each year is represented by a separate radial chart, with dots positioned by day of year and distance from the center encoding weekly average birth count. Built with React and D3.js v7, the chart uses SVG filters for a gooey merging effect and transitions to animate dot positions. Hover interactions enlarge individual dots, and the data comes from a CSV file containing daily live birth statistics.

HAW: Bday Data viz

This visualization compares annual birth statistics across four years by rendering each year as a hospital building, with the number of birth dots inside representing relative crowdedness. React manages the component state and container sizing via a custom `useContainerDimensions` hook, while D3 v7 handles SVG rendering and data joins through `d3.select` and `d3.csv`. The chart pulses with an interactive hover effect on hospital bodies, and the code explicitly generates synthetic multi-year data by applying variations to the loaded CSV totals from `data.csv`.

Fork of CV: Loading CSV Data

This visualization presents daily birth statistics for January–February 2024 as an interactive heatmap, using a viridis color scale to encode birth counts across days of the week and weeks of the month. Hovering highlights individual cells and displays a tooltip with the exact date and birth count, while a stats panel shows peak, minimum, and average values. Built with React and D3 v7, it uses `d3.csv` to load the data, `scaleSequential` with `interpolateViridis` for coloring, and D3 selections with transitions for smooth hover effects and cell rendering.

HAW: Sommer baby Boom

This visualization displays daily birth counts (Lebendgeborene) in Germany for 2024 as a circular, radial chart. It highlights seasonal patterns, with each day represented as a colored dot positioned by date angle and birth-count radius, and users can click dots or hover for tooltips. Built with D3 v7 and React 19, the chart uses `d3.scaleLinear` for positioning and color mapping, drawing SVG circles with a line generator. Data is loaded from a CSV file, and the visualization is responsive via a `ResizeObserver`.

Fork of Fork of Fork of Chart redesign

This example visualizes a time series of daily humidity data as a line chart with overlaid seasonal summaries. The chart uses a colored timeline gradient and highlights distinct season spans (Spring, Summer, Fall, Winter) as shaded rectangles, alongside dotted data points and dashed season mean lines. The visualization is built with React and D3 v5, using `d3.json` to load the dataset, `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.area` with `d3.curveBasis` to generate the smoothed line path. The chart is rendered as an SVG, with downsampling applied to the data for smoother curve rendering.

Fork of HAW: Bday Data viz

This interactive bubble chart visualizes the human toll of terrorist attacks, encoding each incident as a circle whose size and red color intensity correspond to the number of deaths. Built with React and D3 v7, the visualization uses `d3.forceSimulation` to position the bubbles in a force-directed layout, while custom hover interactions with `transition` and event listeners reveal detailed tooltips with the location, date, and death count. The are sized using a linear `radiusScale` and colored via a `colorScale`, both derived from the `attacksData` dataset.

Fork of HAW test 5.12

This interactive scatterplot displays five data points from a CSV file, connected by a line to reveal a downward trend. Clicking a square point highlights it with a white fill and bold black stroke. Built with React and D3 v7, the visualization uses `scaleLinear` for axes, a D3 line generator for the path, and `ResizeObserver` to make the SVG responsive. The `selectAll('rect').join('rect')` pattern renders the clickable points with custom colors.
