This dark-themed line chart visualizes monthly sales data from January 2023 through December 2024, sourced from a CSV file. Built with D3 v7, the reusable `lineChart()` function renders an SVG path using `d3.line()` with `curveMonotoneX`, along with circles for data points. Interactive tooltips appear on mouse hover via D3 event handlers. The chart includes a programmatic `update()` method that animates transitions for axes and the line when new data is provided.

MK Area Chart

This example demonstrates a reusable area chart built with D3 v7, visualizing monthly sales data from a local CSV file across 2023 and 2024. The chart uses a blue gradient fill and a monotone curve, with axes, labels, and a title configured through a fluent API. Interactive tooltips appear on hover, displaying the month and sales value for each data point. The implementation leverages `d3.scaleTime`, `d3.scaleLinear`, `d3.area`, `d3.line`, and `d3.axisBottom`/`d3.axisLeft`, while the `main.js` script parses and sorts the CSV data before invoking the chart. The reusable component supports an optional update method for animated transitions.

LINE CHART

This line chart visualizes monthly sales data for a six-month period, with a smooth monotone curve connecting sales values for January through June. The chart uses D3 v7 with an SVG rendering approach, employing `d3.scaleBand` for the categorical month axis, `d3.scaleLinear` for the sales values, and `d3.line` with `curveMonotoneX` to create the interpolated path. Circular markers highlight individual data points at each month's sales level, while axes are rendered using `d3.axisBottom` and `d3.axisLeft` with labels for "Month" and "Sales."

This example visualizes monthly sales trends from a CSV data source, comparing three product lines from 2019 to 2023. It shows a multi-series line chart with time-scale axes, using D3 v7 and SVG rendering. The code loads data with `d3.csv`, maps dates via `d3.timeParse`, and draws lines with `d3.line`, alongside a legend and axis labels. The second part combines a bar chart for total sales with an overlaid line for average price, using a dual y-axis scale.

Line chart

This line chart visualizes yearly sales data using a time-series line graph. The SVG rendering uses D3.js v7 with `d3.csv` for data loading, `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` for axes, and `d3.line` to generate the path. Data comes from a remote CSV file accessed via a gist URL.

Assignment_7_Q3

This line chart shows monthly sales figures across a calendar year, with a smooth curved line connecting twelve data points from January through December. Users can hover over any circle marker to see a tooltip displaying the exact month and sales value. The visualization uses D3 v7 with SVG rendering, employing d3.scaleLinear for the x and y axes, d3.line with curveMonotoneX for the path, and d3.csvParse for loading the embedded dataset. Axis labels clarify the month and sales dimensions.

LINE CHART

This line chart displays monthly revenue trends over time, with each data point marked by a circle and connected by a steelblue line. The visualization uses D3 v7’s `d3.scalePoint` for the categorical month axis, `d3.scaleLinear` for the revenue scale, and `d3.line` to generate the path. Data is loaded asynchronously from a CSV file via `d3.csv`, and rendered as SVG with axis labels and gridlines.

Fork of Line Chart

This fork of a line chart visualizes monthly sales data for 2022, plotting sales figures against months. The chart uses D3 v5 and renders as an SVG, with a purple line connecting data points. It employs `d3.scalePoint` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.line` to generate the path. Data is loaded from a CSV file via `d3.csv`, with axis labels and a title styled through CSS. The visualization includes gridlines via the y-axis tick size.

Line Chart

This line chart shows monthly value trends across multiple years, with a smooth monotone curve plotted over time. The visualization uses D3.js v7, specifically the `d3.scaleTime` and `d3.scaleLinear` axes, and renders the line via `d3.line` with a `d3.curveMonotoneX` curve. Data is loaded from a CSV file using `d3.csv`, and the chart outputs to an SVG canvas with labeled axes and tick marks. The styling adheres to BBC-like color themes and font choices, though the core plot focuses on the steelblue line and its temporal variation.
