Forked from Hello VizHub

This example demonstrates how to transform raw InfluxDB-style measurement data into a structured JSON payload. It shows a collection of sensor readings (such as pressure, temperature, and power) organized into InfluxDB line protocol objects, each with a measurement name, fields, and index-based tags. The code uses D3 v5’s `select` API to display the resulting JSON in the browser, while local ES6 modules handle data transformation. The `message.js` module iterates over the data keys and builds the output objects, which are rendered as text in the page’s message div.

AI-generated description

An example showing the capabilities of VizHub:

  • Loads D3 via UNPKG.
  • Demonstrates use of import from "d3".
  • Demonstrates use of import from local ES6 modules.

Ingesting-Data

This example fetches a CSV of greenhouse gas emissions by life-cycle stage from a GitHub-hosted Our World in Data upload, then uses `d3.csvParse` to convert the raw text into a structured array. It displays a summary of the data—approximate file size in kilobytes, row count, and column count—in a pre-formatted message area. The code also demonstrates chaining `d3.select`, `append`, and `attr` calls to construct an SVG circle and group, though no data-driven geometry is rendered. The page uses React and ReactDOM loaded via UMD, but the visible output relies on plain DOM text updates.

Transforming Data

A data-transformation example reads the classic Iris dataset from a CSV and computes the average sepal length per species using D3’s `flatRollup` and `sum` APIs. The result is rendered as a formatted JSON summary displayed inside a `<pre>` element, demonstrating the library’s data-wrangling capabilities. The code highlights loading D3 via UNPKG and the use of local ES6 modules alongside a state-management pattern for asynchronous data fetching.

transformingdata

This example displays a simple message, "Hello VizHub!", centered on a plain web page. It demonstrates the fundamental capabilities of the VizHub platform, including loading D3 v5 from a CDN, using D3's `select` function to target an HTML element, and importing a custom string from a local ES6 module (`myMessage.js`). The visualization is minimal, focusing on the integration of external libraries and modular code rather than presenting a data-driven chart.

D3 data transformation

This example demonstrates a simple data-loading and transformation workflow using D3. It fetches a CSV file containing the classic Iris dataset and uses `d3.csvParse` to convert the raw text into an array of objects, subsequently coercing the numeric measurement columns to numbers. The resulting parsed data is displayed as formatted JSON inside a `<pre>` element. The visualization uses a minimal state management pattern, with a `setState` callback triggering re-renders, and leverages D3’s `select` and `join` for DOM updates.

test

This example demonstrates the basic setup for using D3 version 6, displaying a single message extracted from a flower dataset. It loads flower measurements as JSON and displays the first entry’s content in an HTML element. The code uses the native `import` statement to access the data from a local JavaScript module, then manipulates the DOM directly with `document.getElementById` and `textContent`. The visualization serves as a minimal introduction to integrating D3 v6 with modern ES6 module syntax, highlighting the correct import pattern for external data files.

Transforming Data

This example demonstrates how data can be loaded, parsed, and aggregated in the browser using D3 v7 and ES6 modules. It loads the classic Iris dataset from a CSV file, converts the numeric fields, and then uses `d3.flatRollup` with `d3.sum` to compute the average sepal length for each species. The result is displayed as formatted JSON text within a `<pre>` element. The code also illustrates a pattern for handling asynchronous data loading with a state machine that manages `undefined`, `'LOADING'`, and loaded data states.

This example demonstrates a complete Internet of Things workflow, showing how to collect, store, and visualize sensor data from a smart agriculture scenario. It uses an InfluxDB time-series database running on an Amazon EC2 instance to manage temperature, humidity, luminosity, and soil moisture readings. The data is generated by a Mockaroo CSV export and imported through the InfluxDB CLI, then queried with InfluxQL and the Flux language’s `aggregateWindow` function. The final step renders interactive trend charts in the InfluxDB dashboard, illustrating the full path from raw sensor simulation to analytical visualization.

Transforming Data

This example demonstrates a data transformation pipeline using D3.js v7. It loads the classic Iris dataset from a CSV file, parses it with D3's `csvParse` function, then computes the average sepal length grouped by species using `flatRollup` and `sum`. The resulting summary is displayed as formatted JSON text in a `<pre>` element. It showcases how D3's functional API can be used for data aggregation and transformation, with the visualization updating asynchronously via a state management pattern and local ES6 module imports.
