A simple line chart shows monthly values as a single black line with circular gray markers. Hovering a marker turns it red, displays the numeric value in a text label, and draws a dashed vertical guide line to the baseline. The visualization is built with D3 v4, using `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.line` for the path, and `d3.json` to load the data from `dataset.json`. Mouseover and mouseout event handlers dynamically add and remove the tooltip elements and guide line.

DataViz_TP2

This example visualizes a simple line chart of monthly values using D3.js v4, rendering an SVG with a time-scaled x-axis and linear y-axis. It displays labeled data points as light grey circles connected by a black line, with the final value annotated at the end. Hovering over a circle highlights it in red, reveals the corresponding value label, and draws a dashed vertical guide line to the bottom of the chart. The code uses `d3.scaleTime`, `d3.scaleLinear`, `d3.line`, `d3.json` for loading `dataset.json`, and transitions via `transition().style()` for interactive feedback.

TP Data Viz - dynamic line chart

A dynamic line chart plots a synthetic dataset of monthly values from January to December 2016, where hovering over a circular point highlights it in red, shows the value in a text tooltip, and draws a dashed vertical guide to the baseline. The chart uses an ordinal x-scale for categories and a linear y-scale, with the line, circles, and labels rendered as SVG elements. Built with D3 v3, it loads data from a JSON file via `d3.json`, applies date parsing with `d3.time.format`, and uses mouseover and mouseout events to toggle the interactive annotations.

TP 2.1 Interactive Line Chart

An interactive line chart displays twelve monthly data points from January to December 2016, encoded as a black path with gray circles. Hovering over a circle highlights it in red, reveals its numeric value label, and shows a dashed vertical guide line to the x-axis. The chart uses D3 v4’s `d3.scaleTime`, `d3.scaleLinear`, and `d3.line` with SVG elements. Data is loaded from an external JSON file, and all labels and grid lines are rendered as SVG text and line elements with mouse event handlers.

tp2

This example shows a time-series line chart of seven monthly data points, with circles marking each value. Hovering a circle highlights it in red and displays its value as a label, while a dashed red vertical line appears beneath the point. The visualization is built with D3 v4, rendering to an SVG canvas. It uses `d3.scaleTime` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.line` for the path, with data loaded from a local JSON file via `d3.json`.

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.

TP3

A line chart displays monthly values from a small JSON dataset, with circles marking each point. The visualization uses d3.svg.line and d3.scale.ordinal for positioning, while labels show abbreviated month names. Hovering over a circle highlights it in red, reveals its numeric value in black text, and draws a dashed vertical line beneath it; moving the mouse away restores the original grey and white styling. The chart is rendered as SVG with d3.v3.

TP2Devoir

This example displays a simple time series line chart of seven monthly data points from a small JSON dataset, plotting values across dates. The chart encodes values with a black line, light-grey circular markers, and faint dashed vertical guides. Hovering over a circle turns it red, reveals its corresponding value label, and highlights its dashed guide line. The visualization uses D3 v4’s `d3.scaleTime`, `d3.scaleLinear`, `d3.line`, and `d3.timeParse`, rendering to SVG with interactive mouseover and mouseout events.

TP3 area simple line chart

This area chart visualizes a simple dataset of monthly values using a blue filled region beneath a black line. Built with D3 v4, it uses `d3.scaleTime` for the x-axis and `d3.scaleLinear` for the y-axis, with `d3.area` and `d3.line` generating the SVG paths. Data is loaded from a local `dataset.json` file, parsed with `d3.timeParse`, and labeled with formatted month-year strings. The chart also highlights the final value’s numeric label beside the line’s end.
