This example shows a simple line chart of twelve monthly data points, where each point is marked by a red circle. The chart highlights the final value with a large number label and allows interactive exploration: hovering over a point turns it blue and draws a temporary vertical dashed line to the x-axis with the corresponding value displayed. The visualization is built with D3.js v3, using an ordinal scale for the x-axis (categories A–L) and a linear scale for the y-axis. Data is loaded from an external JSON file via `d3.json`, and the line, circles, and text are rendered as SVG elements with CSS transitions for hover effects.

simple line chart from dataset

A simple line chart displays monthly values from a small JSON dataset, plotting each data point as a grey circle. Hovering over a circle turns it red, enlarges it, reveals its numeric value above, and draws a dashed vertical line down to the x-axis. The visualization uses D3 v3 with SVG, employing an ordinal scale for x-positions, a linear scale for y-values, and mouseover/mouseout event handlers to animate the transitions.

simple line chart from dataset

A simple SVG line chart plots monthly values from an 11-point JSON dataset, with a black polyline, labeled x-axis dates, and a large final-value annotation. The visualization adds interactivity through gray circular markers at each data point; hovering a circle turns it red, reveals its value, and displays a vertical dashed guide line. The chart uses D3 v4’s `d3.scaleTime`, `d3.scaleLinear`, and `d3.line`, with mouseover and mouseout events controlling opacity and stroke transitions. Animation effects appear via `transition().duration(300)` when changing marker color and opacity.

simple line chart from dataset

This line chart visualizes a small dataset with monthly values, displaying a black polyline and red translucent circles for each data point. The chart includes a time-based x-axis and a linear y-axis, with the last value printed in large text. The code loads data from “dataset.json” using `d3.json`, parses dates with `d3.timeParse`, and renders the chart with SVG shapes. Hovering over a circle triggers a dashed vertical line and a temporary value label, using D3’s selection and event handlers.

simple line chart from dataset

This simple line chart visualizes a small dataset over time, with each data point represented by a circle that turns red on mouseover and displays its value. The chart uses an ordinal scale for the categorical x-axis and a linear scale for the y-axis, drawing a black polyline through all points. Built with D3 v3, the visualization loads JSON data via `d3.json`, parses dates with `d3.time.format`, and constructs the line using `d3.svg.line`. SVG text elements label the x-axis with abbreviated month names below the chart.

simple line chart from dataset

This example shows a simple line chart of monthly values from a small dataset, with interactive tooltips that reveal each point’s value and draw a dashed vertical guide down to the x-axis. The chart uses d3.scaleTime and d3.scaleLinear for axes, d3.line to generate the path, and d3.json to load the data. Circles are added per data point, and mouseover and mouseout events toggle the tooltip and dash-line visibility. The labels and values are rendered as SVG text elements.

simple line chart from dataset _ Final version

This example shows a monthly time series of twelve data points from a local dataset, with a single black polyline connecting values, labeled x-axis dates, and a large final-value annotation. It also adds light-gray circular markers that turn red on hover, displaying the current value and a dashed vertical guide line. Built with D3 v4, it uses `d3.scaleTime` for the date axis, `d3.scaleLinear` for values, `d3.line` to generate the path, and SVG elements rendered via the code. The dataset is loaded with `d3.json` from a static file, and all interaction logic resides in `mouseover` and `mouseout` event handlers.

simple line chart from dataset

A simple line chart visualizes a small dataset of monthly values, displaying the trend over time with labeled points and a final value annotation. Built with D3 v4, it uses SVG for rendering and includes interactive hover effects that highlight individual data points with circles, reveal their values, and show dashed guide lines. The data comes from a local JSON file, and scales like `d3.scaleTime()` and `d3.scaleLinear()` handle positioning, while `d3.line()` draws the path.

Simple line chart

This simple line chart visualizes a dataset of monthly values from January to December 2016. The chart plots a black line connecting twelve data points, with each point represented by a circle. Hovering over a circle highlights it in red, draws a dashed vertical guide line, and displays the value in a green tooltip. The visualization uses D3 v3, rendering SVG elements with ordinal and linear scales, a D3 line generator, and JSON data loading for the dataset.
