This example visualizes the USD to RUB exchange rate over three selectable years (2018, 2019, 2020) as an animated line chart with a filled area. It uses d3.js v6 within a React-compatible structure, rendering to SVG. Data is loaded from CSV files using `d3.csv`, with the x-axis mapped via `d3.scaleTime` and the y-axis via `d3.scaleLinear`. The line and area paths are built with `d3.line` and `d3.area` using cardinal curves, while transitions (using `transition()`) animate the axis rescaling and stroke-dasharray drawing effect. A mouse hover reveals a crosshair and highlights the nearest data point via `d3.bisector`. The source is the Moscow Exchange, linked via an embedded anchor.

Line chart.js!

This line chart visualizes yearly data from a CSV file, plotting values against years with a blue line on axes labeled "Year" and "Value." It uses D3 v7 to load the data via `d3.csv`, scales the x- and y-axes with `d3.scaleLinear`, and renders the line path using the `d3.line` generator. The chart explicitly appends axes, labels, and the line to an SVG element, with margins set to accommodate tick marks and text. The example demonstrates basic DOM manipulation and data binding in D3.

line chart using d3

This example uses D3.js v7 to create a line chart visualizing restaurant profit trends over recorded years. It loads CSV data from a GitHub gist and maps the year and profit columns to a linear x-axis and y-axis, rendering the line as an SVG path with a steelblue stroke. The chart includes axes labeled "Recorded Year" and "Profit In Million," plus an interactive tooltip that displays the data values on mouse movement. The SVG container is configured with custom margins, and the entire chart is styled with a black background and white text via CSS.

React and D3 Line Chart

This example shows a React and D3.js line chart that displays data loaded from a remote CSV file. The visualization uses React state to manage the data loading process, initially displaying a “Loading…” message until the data is fetched. D3 utility functions like `csv()` are used to parse and transform the data, while React’s `useState` and `useEffect` hooks handle the asynchronous data retrieval. The chart renders as an SVG, though the current implementation displays only a placeholder circle, with the data being mapped but not yet visualized as lines.

Line Chart with label V2

This line chart displays Google stock prices (open, high, low, close, and volume) over time from March 2016 to March 2021, using data loaded from a CSV via `d3.csv`. Built with React and d3.v5, the visualization uses `scaleTime` and `scaleLinear` for axes, and a `line` generator with `curveStep` to render the closing price trajectory. A crosshair cursor with `bisector` and `xScale.invert` enables interactive tooltips showing detailed values for each date.

Line Chart- Data Visualization

This line chart displays Amazon’s stock price over time, with the year on the x-axis and price on the y-axis, using an SVG rendered with D3 v5. It loads a CSV dataset via `d3.csv`, parses dates with `d3.timeParse`, and maps data using `scaleTime` and `scaleLinear`. The chart includes labeled axes with gridlines, and draws the price trend as a single line path generated by `d3.line`.

Basic line chart

This line chart shows the relationship between two numerical values and time, plotting two series from a CSV file across the years 2010–2015. It uses d3.csv to load the data, then applies d3.scaleTime and d3.scaleLinear for axes, while d3.line constructs the paths. The chart renders in SVG, with each line styled via a separate stroke color. Axis labels are added using d3.axisBottom and d3.axisLeft, and the code includes configurable column names for easy reuse as a template.

Line Chart

This line chart displays closing values over time, using a smooth natural curve to connect data points. The chart renders as an SVG with React components, leveraging D3 v5 functions including `scaleTime`, `scaleLinear`, `extent`, and `timeFormat` for scales and axes. Data is loaded asynchronously from a CSV file via `d3.csv` and parsed into Date objects. The visualization includes labeled x and y axes with tick marks, while the line itself uses a teal stroke with rounded joins, omitting point markers as indicated in the commented-out circle elements.

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.
