Forked from D3 Starter

This example shows the monthly sales trend from 2021 to 2025 as a smooth line chart. The chart displays a single steelblue line with orange data points, with rotated month labels on the x-axis and a linear y-axis. Built with D3 v6, the code uses `d3.csv` to load `sales_trend.csv`, `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.line` with `d3.curveMonotoneX` for the smoothed path, and `d3.axisBottom` and `d3.axisLeft` for tick marks. The SVG rendering includes a title and axis labels.

AI-generated description

Monthly Sales Trend Visualization

This project visualizes monthly sales data from 2021 to 2025 using D3.js.

Files

  • index.html: Main HTML file
  • index.js: JavaScript implementation for the line chart
  • sales_trend.csv: Sales data by month

How to Run

  1. Open index.html in a web browser
  2. The line chart will automatically load and display the sales trend

Data Format

The CSV file contains two columns:

  • month: Month and year in format "MMM-YYYY" (e.g., "Jan-2021")
  • sales: Sales figures for that month

This line chart visualizes monthly sales growth from January 2021 to January 2025 using a smooth monotone curve. The SVG rendering relies on d3.scaleTime, d3.scaleLinear, d3.line with curveMonotoneX, and d3.axisBottom/axisLeft, with data loaded via d3.csv from sales_trend.csv. Orange circles mark individual data points, while labeled axes and a title clarify the upward trend.

Fork of third

This line chart visualizes monthly sales growth from January 2021 through January 2025, showing a steady upward trend from 420 to 1,195 units. The chart is rendered as an SVG using D3.js v6, with a monotone-smoothed blue line and orange circular markers at each data point. The time-series data is loaded from a CSV file and parsed using `d3.timeParse`, with scales set via `d3.scaleTime` and `d3.scaleLinear`, and axes drawn using `d3.axisBottom` and `d3.axisLeft`. Rotated month labels and custom titles complete the visualization.

This area chart displays monthly sales growth from 2021 to 2025, with a monotonically increasing trend from 420 to 1,320 units. The visualization loads data from a CSV file, parses dates with `d3.timeParse`, and renders the area using D3's `d3.area` generator with a monotone X curve. It includes formatted axes, rotated month labels, grid lines, and clear axis labels for readability. The SVG output is styled with a light background and a shaded area against a steel-blue stroke.

This area chart displays monthly sales growth from January 2021 through January 2025, showing a steady upward trend in units sold. The D3.js v6 visualization uses `d3.area()` with `d3.curveMonotoneX` to render a smooth filled path, with lightsteelblue fill and steelblue stroke. The code loads data from a CSV file via `d3.csv()`, parses dates with `d3.timeParse()`, and constructs time and linear scales using `d3.scaleTime()` and `d3.scaleLinear()`. Grid lines are added through custom axis configurations, while rotated month labels and axis titles provide context. The SVG output includes a white background, rounded corners, and a subtle shadow effect.

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 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.

3 Line Chart

This visualization shows monthly revenue trends across a year using a green line and red circular data points. The chart is built with D3 v7 and rendered as an SVG, using `d3.scalePoint` for the month axis and `d3.scaleLinear` with `.nice()` for the revenue axis. A monotone X curve smooths the line via `d3.curveMonotoneX`, while `d3.axisBottom` and `d3.axisLeft` generate the labeled axes, with data loaded from a CSV file.
