The visualization displays how often different colors appear in regional flags, using flag images and region data from Wikipedia. It shows a stacked bar chart for each country, with colored segments representing the proportion of each color across its subnational flags. The left panel lists countries and their color distributions; hovering over a segment filters and sorts the corresponding flag thumbnails on the right. The implementation uses d3.select, d3.nestBy, and d3.loadData, with custom color bucketing based on hue and lightness, rendered as SVG rectangles and HTML images.

How often do different colors show up in regional flags?

Based on Time's “What is the Most Patriotic Color?” and suggested by Jennifer Daniel

Flag images and region list from wikipedia; scrapping code.

Gist 5475820

This example shows a small grid of colored cells tracking how country rankings change over time. The visualization uses a dataset with six countries and seven years (2003–2009), where each cell’s color encodes a rank value from 1 to 6. The code reshapes the data into a flat array of year–country–value triples, then draws SVG rectangles with `d3.select` and `.enter()`. It uses `d3.scale.quantize` for the color scale and `d3.scale.ordinal` for positioning. Hovering turns a cell white, and clicking logs the selected element to the console.

Show National Contiguity with a Force Directed Graph - D3.js

This example visualizes national contiguity using a force-directed graph, where each country is represented by a flag sprite node and connections between bordering nations are shown as red links. It uses D3 v3’s `d3.layout.force` to simulate the physical layout, with nodes and links animated over time as the simulation runs. Hovering over a flag triggers a tooltip displaying the country name. The data is loaded asynchronously from a remote JSON file hosted on GitHub.

Scatter Plot

This scatter plot displays the number of occurrences for each nation, with country names on the y-axis and values on the x-axis. The visualization uses D3 v6 with SVG rendering, importing `select`, `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, `axisBottom`, and `format` from D3. Data is loaded from a local CSV file, with values multiplied by 1000. Rectangles represent each country, scaled proportionally to their numeric values, with formatted tick labels using `format('~s')` to abbreviate large numbers.

Assignment2_Ques2

This stacked bar chart visualizes tourist counts by region over time, with yearly totals aggregated on the y-axis and regions distinguished by color. Built with Vega-Lite through the vega-lite-api and D3, the visualization loads CSV data from a GitHub Gist and renders as a responsive SVG. Tooltips provide detailed per-region tourist values, while custom styling via the config object colors axis labels and titles in a dark purple.

D3 Country Bubble Chart

This bubble chart displays each country as a circle scaled by population, with hover tooltips showing the country name and population. Interactive radio buttons switch between grouping modes—combining all bubbles, clustering by continent, positioning at country centers, or sorting by population—and toggle circle fills between continent colors and country flag patterns. The visualization uses d3.forceSimulation with custom force configurations for each grouping, d3.scaleSqrt for radius scaling, and SVG patterns for flag fills. It loads data from a CSV file and animates transitions between the different layouts.

Project | Load color | legend | moving

This example displays a world map with countries colored by a categorical measure of "prudence," using a yellow-or-red ordinal color scale. An interactive legend allows users to click a color value to filter and highlight matching countries while dimming others. The visualization uses d3.geoPath with a geoEquirectangular projection, d3.zoom for panning, and a custom color legend component. Data comes from CSV and TopoJSON files, rendered as SVG paths with hover effects defined in CSS.

Most visited countries

This visualization presents a pie chart of the most visited countries, using a legend to display each country's name alongside its tourist count in millions. The chart is rendered as SVG using D3 v5, with the `d3.pie` layout and `d3.arc` segments forming the chart, while a categorical color scale from `d3.scaleOrdinal` assigns distinct colors. Data is loaded from a CSV hosted on GitHub via a gist URL, and tourist figures are formatted with the `d3.format` function.

practice svg

This example shows a simple bar chart of region values using SVG rectangles rendered through D3. The chart displays five data points with regions such as USA, Nigeria, and Ghana, mapping each value to a bar height via d3.scaleLinear and positioning bars with d3.scaleBand. The SVG container is styled with CSS, and the bars are appended dynamically using d3.select and the enter selection pattern, with data bound from a static array. The x-axis uses padding and range rounding for layout.
