This example shows a comparative area chart of monthly sales for two products during 2023, filled with distinct colors from a categorical scheme. The chart uses D3 v7’s `d3.scaleBand` for the month axis and `d3.scaleLinear` for the sales axis, with area paths generated via `d3.area`. Data is fetched as CSV from a GitHub repository, parsed with `d3.csvParse`, and rendered as SVG. A custom HTML legend, built with `d3.select` and `d3.selectAll`, displays color swatches and product labels alongside the chart.

Assignment2Question2

This D3.js v7 example creates an SVG area chart that visualizes monthly sales data for two products during 2022. The chart displays values from the embedded data array, with product1 and product2 each shown as filled areas using `d3.area()` and a categorical color scale via `d3.scaleOrdinal` with `d3.schemeCategory10`. A legend is generated using D3’s selection API to map colors to product names, while axes are created with `d3.axisBottom` and `d3.axisLeft`, and data is scaled using `d3.scaleBand` and `d3.scaleLinear`.

Act7Question2

A monthly sales area chart visualizes sales figures across twelve months, with a green shaded region emphasizing the trend and volume of sales over time. Built with D3.js v7, it fetches CSV data from a GitHub repository and uses `d3.scaleBand` for the month axis, `d3.scaleLinear` for sales, and an `d3.area` generator to produce the filled path. The SVG rendering includes labeled axes and grid-free styling with a responsive container.

Assignment2 question 2

This example displays a filled area chart that visualizes sales trends over months, using data fetched from a GitHub Gist CSV file. The chart is rendered as an SVG using D3 v7, employing `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for the numeric y-axis, and `d3.area` to generate the shaded region. Axis labels for "Sales" and "Month" are added via `d3.axisLeft` and `d3.axisBottom`.

Activity-6 (question2.1)

This chart displays monthly sales figures for three product categories—Electronics, Clothing, and Home Goods—as a stacked horizontal bar chart. D3’s `scaleBand` positions months on the y-axis, while a `scaleLinear` maps cumulative sales values to x-axis lengths. Each bar segment’s width corresponds to category-specific revenue, with a legend and interactive tooltips revealing exact dollar amounts on hover. The example loads D3 v7 via UNPKG, reads CSV data asynchronously, and constructs the SVG visualization using `d3.axisLeft`, `d3.axisBottom`, `d3.stack`, and `scaleOrdinal` for color encoding.

Act 7_Question 2

This example renders a monthly sales area chart in SVG using D3 v7. It shows how sales values increase from January through December, with the area filled in steel blue beneath a line marking the data points. The chart manually constructs axes by applying `d3.axisLeft` for the y-axis and placing custom text labels for each month using `d3.scaleBand`. An `d3.area` generator defines the path, while `d3.scaleLinear` maps sales values to vertical positions, and margins control the layout.

Question 4: Area Chart

This area chart visualizes monthly revenue trends across multiple products, with each product represented as a colored filled region that can be hovered to adjust opacity. The chart uses D3 v7 to load CSV data via `d3.csv`, aggregates revenue by product and month using `d3.group` and `d3.rollup`, and renders the areas with `d3.area` alongside scaled point-based x-axes (`d3.scalePoint`) and linear y-axes (`d3.scaleLinear`). Interactive dots respond to mouse hover by increasing their radius, and gridlines provide reference for revenue values.

Question2

The visualization compares units sold in 2019 versus 2020 across multiple item categories using two filled area paths rendered in SVG. D3.js v7 fetches a CSV dataset via `fetch` and `d3.csvParse`, then constructs a band scale for the x-axis and a linear scale for the y-axis. The areas are generated with `d3.area()`, colored using `d3.scaleOrdinal` with `d3.schemeCategory10`, and accompanied by an HTML legend with color swatches. Axis titles and rotated tick labels clarify the data mapping.

Task9-Question2

This area chart visualizes smartphone sales across multiple months, with distinct colored regions representing different product lines or years. The visualization uses stacked areas to show the cumulative contribution of each category over time, making it easy to compare relative proportions. Built with D3.js v7, the chart loads CSV data from a GitHub repository and uses d3.stack, d3.area, and d3.scaleBand to construct the stacked layout. SVG rendering handles the paths, axes, and rotated month labels, while a custom HTML legend with colored circles identifies each series.
