This pie chart visualizes the distribution of drug types from a CSV dataset of 200 patients, showing the count of prescriptions for each drug. The chart uses D3 v7’s `d3.pie()` and `d3.arc()` to generate SVG arcs, with a categorical color scale (`d3.scaleOrdinal` with `d3.schemeCategory10`) for segment fills. Data is aggregated via `d3.group()`, and each slice includes a white value label. A legend on the right maps colors to drug names, rendered as SVG rectangles and text.

Task9_Question1

A pie chart visualizes the distribution of patient counts by race, with each slice labeled directly and accompanied by a color-coded legend. The chart loads CSV data from a GitHub gist and uses D3 v7 APIs including `d3.rollup` to aggregate counts, `d3.pie` for layout, `d3.arc` for slice geometry, and `scaleOrdinal` with `schemeCategory10` for colors. Labels are positioned using `arcGenerator.centroid`, and the SVG rendering is centered within a 400×400 canvas.

Question 1 pie chart

A pie chart visualizes the distribution of total sales across item categories, with values aggregated and labeled directly on each slice. The chart includes a legend and titles indicating the overall sales scope. It uses D3 v6 APIs including `d3.pie`, `d3.arc`, and `d3.rollups` to aggregate and render the data, with color encoding via `d3.scaleOrdinal`. The data is loaded as a CSV from a GitHub Gist, and the visualization is rendered as an SVG.

Question 1

This pie chart visualizes fruit sales data, displaying the proportional share of each fruit category as a labeled slice with a corresponding legend. The chart is rendered as an SVG using D3 version 7, with the pie generator `d3.pie()` and arc generator `d3.arc()` calculating angular extents and centroids for labels. Data is loaded via `d3.csv` from a remote Gist, and the color scale `d3.scaleOrdinal` with `d3.schemeSet2` assigns categorical colors. The legend is built using `d3.select` and `enter()`, while sales values are cast to numeric type before creating the pie layout.

question_1

This pie chart shows the distribution of insurance records across four regions—southeast, southwest, northeast, and northwest—using data loaded from an external CSV file. The chart uses D3 v7’s `d3.pie`, `d3.arc`, and `d3.rollups` to aggregate and visualize the counts, with a categorical color scale (`d3.scaleOrdinal`) assigning distinct colors. Each slice is labeled with its region name via arc centroids, and a legend is rendered using SVG rectangles and text elements, all positioned within a 600x600 SVG container.

Question1

This pie chart visualizes product sales distribution, with each slice sized proportionally to its revenue share and a corresponding legend displaying category names and percentage values. The chart uses d3.pie and d3.arc to generate the SVG paths, with a scaleOrdinal color scale assigning distinct hues to each segment. Data is loaded asynchronously from a CSV via d3.csv, and percentage labels are formatted with d3.format. The total sum of all values is calculated to compute each category’s share.

Question 1

This pie chart visualizes sales distribution by product category, using a categorical color scale to differentiate segments and displaying numeric values directly inside each slice. It loads CSV data from a GitHub Gist, converts the values to numbers, and renders the chart with d3.pie, d3.arc, and d3.scaleOrdinal. A custom legend built with SVG rectangles and text identifies each category, while positional labels for "Product Categories" and "Sales Value" reinforce the chart’s context. The visualization uses D3 v7 with an SVG-based rendering approach.

question-1

This example displays a pie chart visualizing disease frequencies, with sample data showing counts for Hypertension, Diabetes, and Arthritis. The chart uses D3 v7 to generate arcs via `d3.pie()` and `d3.arc()`, with an ordinal color scale from `d3.schemeCategory10`. It renders SVG paths and includes a separate HTML legend built with D3 selections, listing each disease and its count. The code also demonstrates ES6 module imports and axis label placement using SVG text elements.

Question 1 pie chart

This pie chart visualizes total sales distribution across item categories, with each slice labeled by category name and dollar amount. The chart uses D3.js v6 APIs including `d3.pie`, `d3.arc`, and `d3.rollups` to aggregate CSV data by category, with the legend and title rendered as SVG elements. Data is loaded from a GitHub Gist URL and displayed using an SVG canvas with ordinal color scaling.
