This example shows the distribution of Titanic passengers across first, second, and third class, with percentage labels overlaid on each slice. A simple SVG pie chart is generated using D3 v7’s `d3.pie` and `d3.arc` layouts, with each slice filled by a hard-coded color and separated by white strokes. The dataset is hard-coded as three objects containing class name, count, and color. Labels are positioned via the arc `centroid` method and rendered as multi-line text elements showing both class and percentage.

Act 7 Q1

This pie chart visualizes the distribution of passenger classes in the Titanic dataset, showing three categorical slices for Class 1, 2, and 3. The chart uses D3 v7 with an SVG renderer, employing `d3.pie()` and `d3.arc()` to generate the arcs and `d3.rollups()` to aggregate class counts from a CSV. A custom legend displays exact passenger numbers, while axis labels are added despite the circular layout. The color scale maps distinct colors to each class using `d3.scaleOrdinal`.

Pie Chart of Titanic

This pie chart visualizes survival outcomes for Titanic passengers, splitting the dataset into green "Survived" and red "Not Survived" slices with value labels and a legend. It loads CSV data from a GitHub repository using `d3.csv`, aggregates counts via `d3.rollup`, and generates the chart with `d3.pie` and `d3.arc`. Hover interactions trigger a scale transition on slices, while SVG text elements provide axis labels and legend annotations. The visualization renders entirely in SVG with D3 v7.

A2 - Passengers per Class (Dot Plot)

This dot plot visualizes the number of Titanic passengers per class using p5.js, with CSV data loaded via the `loadTable` function from a GitHub gist. The sketch counts passenger records by class and renders three circles with labels, revealing an inverse relationship between class affluence and passenger count. A light blue background, axis lines, and annotations highlight the trend. The visualization displays passenger counts (Class 1: 216, Class 2: 184, Class 3: 491) on a canvas sized to the window, with axes labeled from 0 to 300 in increments of 100.

pie chart ice 7

This chart displays the average fare paid by passengers in each of the three Titanic classes, showing a clear price decline from first to third class. The chart uses a monotone area graph where the x-axis represents passenger class from 1 to 3, and the y-axis shows the average fare in dollars. The visualization is created with D3 v7, using `d3.area` to render the path, along with `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` for the axes, and `d3.select` for DOM manipulation. The source data is a predefined array of three averages computed from the passenger records in `data.csv`.

SDA HW2-1

This example shows the survival distribution of Titanic passengers with a pie chart comparing the counts of survivors and non-survivors. D3 v5 loads the dataset via `d3.csv` from a GitHub gist, aggregates counts using `d3.rollup`, and renders the chart with `d3.pie` and `d3.arc` into an SVG. The visualization includes labels at each arc’s centroid via `arc.centroid`, a color scale from `d3.schemeSet2`, and an interactive legend built with D3 selections. Axis titles and a chart heading are added as SVG text elements.

Fork of Assignment 2 - Pie Chart

A static pie chart displaying the survival distribution of Titanic passengers, split into two categories: "Survived" and "Not Survived." The chart reads data from a remote CSV file, parsing each row to increment counts based on the survival flag. It is rendered as an SVG using D3 v7, with slices drawn via `d3.arc` and positioned by `d3.pie`. The visualization includes a title, color-coded slices, and a simple legend, all styled with inline SVG attributes and CSS rules.

SDA HW2-1

This pie chart visualizes the survival rates of Titanic passengers by splitting the dataset into two categories: non-survivors (0) and survivors (1). The chart uses a purple and green color scale to distinguish between the two groups, with labels showing the count for each category. Built with D3 v6, the visualization loads CSV data from a GitHub gist and uses the `d3.pie()` and `d3.arc()` functions to generate the SVG slices. A legend to the right of the chart displays the color-keyed categories, while text annotations label the axes as survival count and passenger total.

titanic

This D3.js v7 visualization presents a pie chart of passenger survival outcomes from the Titanic disaster, sourced from a CSV file hosted on a GitHub Gist. The animation highlights each slice on hover using a scale transform. The code employs `d3.pie`, `d3.arc`, and `d3.rollup` to aggregate survivor counts, with an SVG renderer and a color scale distinguishing survivors (green) from non-survivors (red). The chart also includes labeled slices, a legend, and axis titles for survival status and passenger counts.
