This area chart shows how three categories—A, B, and C—trend upward from 2010 to 2024, with stacked filled regions emphasizing their cumulative growth. The visualization uses Plotly.js’s `Plotly.newPlot` to render scatter traces with `fill: 'tozeroy'` and `fill: 'tonexty'` modes, creating layered area shading. Data is hardcoded as arrays in the script, with category names assigned via the `name` property. The layout specifies axis titles and the overall chart title.

Questuion 2

This example displays a stacked area chart comparing three categories (A, B, C) over a five-year span from 2010 to 2014. The visualization uses D3.js v7, specifically the `d3.stack`, `d3.area`, `d3.scaleBand`, and `d3.scaleLinear` functions to compute the stacking and generate the SVG paths. Each category is colored using the categorical palette `d3.schemeCategory10`. The chart includes labeled axes for year and value, with margins applied to the SVG canvas for proper layout.

test

This example presents a dynamic area chart showing trends for three categories—CategoryA, CategoryB, and CategoryC—across different years. The visualization uses Plotly.js to render the data, which is fetched from a remote CSV dataset hosted on GitHub. Each category is displayed as a filled line trace, with CategoryA filling to zero and the others stacking on top. The chart includes axes labeled "Year" and "Values," with a title indicating the dynamic nature of the category trends.

This stacked area chart visualizes how three categorical values (A, B, and C) contribute to a total across five years, from 2010 to 2014. The chart uses translucent areas with a category-10 color scheme to show the changing composition over time. Built with D3.js v7, the implementation stacks the dataset using `d3.stack`, scales the X-axis with `d3.scaleBand`, and the Y-axis with `d3.scaleLinear`. Paths for each area are generated via `d3.area`, and the SVG axes are rendered using `d3.axisBottom` and `d3.axisLeft`.

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`.

Assignment 2 Area Chart

This example presents a stacked area chart displaying population data across multiple countries. The visualization uses D3.js v6 to load CSV data, stack series with d3.stack, and render areas with d3.area, while d3.scaleBand and d3.scaleLinear position the categorical and numeric axes. The SVG output includes axis labels, a color-coded legend, and numeric value labels atop each segment. A d3.scaleOrdinal with the schemeCategory10 palette assigns distinct colors to each population category.

Assignment2_Question1(AreaChart)

This area chart visualizes long-term sales performance across four regions (North, South, East, West), using a stacked layout to show the total sales composition by year. Built with D3 v7, it reads CSV data, parses years, and applies `d3.stack()` with `d3.stackOffsetNone` to create the layered areas, colored via `d3.schemeCategory10`. The chart includes axes, labels, and a legend, with interactive tooltips that display region-specific sales values on mouseover using the `pointer-events` attribute and custom HTML tooltip styling.

Question 2

This area chart displays yearly values as a single filled region, showing the trend of data over time. The visualization uses D3.js v6 with a linear scale for both axes and an area generator to create the steelblue path. Data is loaded from a GitHub Gist CSV file and rendered as an SVG, with axis labels added using d3.axisBottom and d3.axisLeft.

Assignment2 question 2

This example shows a monthly sales trend as a filled area chart, with twelve data points from January through December. The visualization uses D3 v7 to render the chart as SVG, employing `d3.scaleBand` for the month axis, `d3.scaleLinear` for the sales axis, and `d3.area` to generate the semi-transparent steel-blue area path. The chart includes labeled axes for both months and sales values. The sample dataset is hardcoded in the script, and the rendering is handled entirely through D3’s SVG manipulation.
