Network Graph

This network graph visualizes relationships among six people using a force-directed layout. It loads data from an external JSON file specifying nodes and weighted links, then renders nodes as orange circles with name labels and green lines for connections. The example uses D3 v4 and v2 APIs simultaneously, relying on `d3.layout.force` to simulate the physical forces that position the nodes. Link thickness scales with the square root of each connection’s weight, while a tick handler updates the SVG elements’ positions during the simulation.

Tree Diagram

This interactive tree diagram displays hierarchical animal classification data from a JSON file, with nodes that collapse and expand on click. Built with D3 v3, it uses the `d3.layout.tree` for layout and `d3.svg.diagonal` for curved links, with SVG rendering and animated transitions between states via `transition.attr`. Node styling includes green circles and comic sans labels, while purple links highlight parent-child relationships.

country map

This visualization displays a choropleth map of the United States, coloring each state in red with thin black internal borders. The map is rendered using React and D3 v5, with geographic shapes generated through `d3.geoAlbers` projection and `d3.geoPath`. State boundaries come from the US Atlas TopoJSON dataset, processed via `topojson.feature` and `topojson.mesh`. The SVG paths change to sky blue on hover using CSS, providing simple interactivity.

ICE 8 Making Maps

This example visualizes the world map using a Natural Earth projection, displaying land masses, country interiors, and a graticule grid over a pale sphere. The map is rendered with SVG paths created via `d3.geoPath` and `geoNaturalEarth1`, while country boundaries are derived from the World Atlas TopoJSON dataset using TopoJSON’s `feature` and `mesh` functions. Land areas are filled with a teal color, with stroke styling applied to the graticule and interior borders. The visualization is built as a React component that loads geographic data asynchronously with `d3.json`.

ICE 7 Area Chart

This visualization shows supermarket sales over years as a smooth area chart, with the area beneath the curve filled to emphasize sales volume trends. It uses D3 v5’s `scaleLinear` for both axes, `area()` and `line()` generators with `curveBasis` for smoothing, and `axisBottom`/`axisLeft` for labeled axes. The chart renders as an SVG in a React framework, loading data from a CSV fetched via `csv()`, with tick formatting applied via `format('.3s')`.

ICE 7 LINE CHART

This interactive line chart visualizes humidity levels in Delhi over time, with the date on the x-axis and humidity percentage on the y-axis. Built with React and D3 v5, it loads CSV data from a GitHub gist and renders an SVG line using `d3.line`, `d3.scaleTime`, `d3.scaleLinear`, and `d3.axisLeft`/`d3.axisBottom`. The chart includes labeled axes, a title, and margins, fixing the y-axis domain from zero to the maximum observed humidity value.

ICE 7 Pie Chart

This pie chart visualizes the number of matches won by each team from a CSV dataset, with a legend detailing team names alongside their corresponding win counts. The visualization uses D3 v5's `pie`, `arc`, `scaleOrdinal`, and `schemeCategory10` APIs to generate SVG paths, while the React-based code appends legend rectangles and text elements within the SVG canvas.

ICE 7 Reusable scatter plot

This reusable scatter plot visualizes the Iris Dataset, mapping petal width, sepal width, petal length, and sepal length onto the x-axis while keeping sepal length on the y-axis. It uses D3’s `scaleLinear`, `scaleOrdinal`, and `symbol` to encode species with distinct SVG path shapes. The plot cycles through the four x-axis variables every two seconds via `setInterval`, re-calling the chart with updated accessors. Rendering is fully SVG-based, with axes generated by `axisLeft` and `axisBottom`, and the viewport resizes to the full window dimensions.

ICE 6 Penguin Dataset

This scatter plot visualizes penguin data from a CSV file, mapping flipper length on the x-axis and body mass on the y-axis while coloring each point by species (Adelie, Gentoo, or Chinstrap). The code loads the dataset using `d3.csv`, parses numeric fields, and renders circles with `d3.selectAll` and `.join`, using `d3.scaleLinear` for axes and `d3.axisLeft`/`d3.axisBottom` for tick marks. The SVG output includes custom axis labels and a title.

ICE 6 Marks and Channels

A horizontal bar chart displays the sales figures for the top 15 supermarket customers. Each bar’s color alternates between red and light blue based on its array position. The chart uses React with D3 v5’s `scaleBand` and `scaleLinear` to position bars, while axis ticks are generated manually from the scales. Data is loaded from a CSV file via `d3.csv` and rendered as SVG rectangles.

ICE 5 CSCE 5320 SCIENTIFIC DATA VISUALIZATION

This example demonstrates how to begin using D3 version 6 by loading a customer card transaction dataset from a CSV file and displaying its metadata. It shows the dataset’s size in kilobytes, row count, and column count within a preformatted text container. The visualization uses the D3.js library’s `d3.csv` method to fetch and parse the external CSV, and `d3.csvFormat` to calculate data size. The page is styled with a custom background image and centered headings via CSS.

Fork of Let's make a face with D3.js!

A smiley face composed of SVG shapes animates its eyebrows in a looping sequence. The code builds the face using D3 selections, appending circles for the head and eyes, rectangles for brows, and a path from `d3.arc` for the mouth. Eyebrow movement is driven by chained `transition().duration(2000)` calls that shift the group’s `transform` attribute between two positions. The example demonstrates fundamental DOM manipulation and animation with D3 v5.

Fork of Smiley Face Part V

A smiling face is drawn with a yellow circular background, black outline, two eyes, and a curved mouth, all rendered as SVG shapes. The visualization is built with React components, with each facial feature defined in a separate file using ES6 modules and React Fragments. The mouth uses D3's `arc` function to generate the path, while the overall layout positions elements relative to the center of a 960x500 SVG canvas. ReactDOM renders the composed SVG to the page.

ICE4

A yellow circle with a black outline occupies the center of an SVG canvas, representing a face in progress. Two smaller black circles act as eyes, positioned symmetrically to the left and right of the face’s upper area. The rendering relies on three SVG `<circle>` elements, with the main face sized at 960 by 500 pixels and the eyes offset from the center via hardcoded `cx` coordinates. The code does not use any JavaScript libraries, instead directly embedding circle geometry and styling attributes in the markup.

ICE4 dj3

This D3.js example shows a large yellow smiley face with circular eyes and an arc-shaped mouth, animated by a pair of rectangular eyebrows that shift vertically in a repeating two-second loop. The SVG elements are constructed programmatically using D3's `select`, `append`, and `attr` methods, while the eyebrow animation relies on D3's `transition` API with a sequence of timed `attr` transforms. The illustration uses no external data source, instead generating its geometry from hardcoded constants for spacing, radii, and offsets within a 960-by-500 viewport.
