The visualization displays US city population trends through two paired charts: a multi-series line chart comparing simulated population values for 2020, 2022, and 2024, and a combined bar-and-line chart showing 2020 bars with an overlaid growth-rate line. Built with React and D3 v7, it renders to a single responsive SVG using a viewBox. Data comes from a CSV file via `d3.csv`, with additional quantitative series generated through a seeded `mulberry32` random number generator. The implementation uses `d3.axisLeft` for grids, `d3.scaleLinear` for scaling, and a linear index-based x-axis.

Fork of Refactored Bar chart with React & D3

This fork of the refactored bar chart example uses React with D3 v7 to render a horizontal bar chart of US city populations. The code defines reusable components for axes and marks, using `d3.scaleLinear` and `d3.scaleBand` to map population values and city names, while data is embedded and parsed via `d3.csvParse` from a local CSV string. Bars are drawn as SVG `rect` elements with hover opacity changes, and gridlines are created through a D3 axis call.

Fork of Stylised Bar chart

This horizontal bar chart displays populations for US cities, sorted in descending order with bars extending along a linear population scale. Built with React and D3 v7, it uses `d3.csv` to load data from a Gist-hosted CSV file and `d3.axisBottom` and `d3.axisLeft` for axes. The chart applies `scaleBand` for city categories and `scaleLinear` for population values, rendering bars as SVG `rect` elements with optional value labels via `d3.format`. A custom axis component adds faint vertical gridlines.

Fork of refactoring bar chart with react and d3

This interactive bar chart displays population data for ten countries, sourced from a CSV file, using horizontal bars to encode each country's population value. Built with React and D3.js v7, the visualization renders entirely as SVG elements, with the `AxisBottom`, `AxisLeft`, and `Marks` components constructing the tick marks, axis labels, and rectangular bars. The chart uses D3's `scaleBand` for the categorical country axis and `scaleLinear` for the numeric population axis, while React's `useState` and `useEffect` hooks manage asynchronous data loading.

Fork of Fork of HTML Starter - Rajan Shah

This animated scatterplot visualizes the population growth of U.S. cities by comparing 2020 and 2024 population figures on the x- and y-axes, with point size reflecting the absolute growth rate. Built with D3.js, it uses a custom scatter chart function that joins SVG circles with data, animating their entry, update, and exit via `.transition().duration()` calls. The code loads city data from a CSV file, applies linear scales, and includes an interactive tooltip that displays city specifics on mouseover.

Fork of Stylised Bar chart

This horizontal bar chart displays the populations of major US cities in millions, using rectangles whose length encodes value and whose vertical position encodes city. Built with React and D3 v7, the visualization loads data from a remote CSV, applies a linear scale for the population axis and a band scale for the categorical city axis, and includes gridlines, axis labels, and hover opacity effects for readability.

Fork of Refactored_bar_chart

This bar chart displays the 2020 population estimates for ten countries, using horizontal bars ordered by country name. The visualization is built with React and D3 v7, where `d3.scaleBand` positions the categorical y-axis and `d3.scaleLinear` maps population values to bar widths. SVG rectangles are rendered through the custom `Marks` component, with axes generated by `AxisBottom` and `AxisLeft`. The data originates from a CSV file of UN Population 2019 data, loaded asynchronously and processed to extract the 2020 values.

Fork of Fork of D3 Scatter Plot -Rajan

This scatter plot ranks major US cities by population magnitude, with each circle’s position and radius encoding the city’s population in millions, while a blue color gradient adds an extra visual cue. The chart loads a CSV from a GitHub gist and uses `d3.csv` with `d3.autoType` to parse the data. It draws axes, gridlines, and labels using `d3.axisLeft`, `d3.axisBottom`, and SVG text elements, while `d3.scaleLinear`, `d3.scalePoint`, and `d3.scaleSqrt` map population to x-position, city name to y-position, and circle size, respectively. Interactive tooltips appear on hover via `d3.select` and mouse events.

Fork of Refectoring a Bar Chart

This visualization displays the population of ten countries as a horizontal bar chart, rendered as SVG elements within a React application. The chart uses D3 scales (`scaleBand` and `scaleLinear`) to map country names and population values to screen coordinates, while React components like `AxisBottom`, `AxisLeft`, and `Marks` manage the rendering of axes and rectangles. Data is loaded asynchronously from a CSV file using D3’s `csv` utility, with population values parsed from the 2020 column.
