С 2015 по 2023 годы редакторам было доступно расширение Graph для визуализации данных между проектами Викимедиа. В сотнях тысяч статей Википедии были размещены графики для обогащения текстового контента. В 2023 году это расширение было отключено по соображениям безопасности. В результате редакторы были расстроены тем, что читатели перестали видеть графики, в создание которых было вложено много времени и сил.

Фонд Викимедиа обсудил будущее графиков с членами сообщества, и этот проект является результатом этих обсуждений. Мы создаем новый безопасный инструмент, который мы называем Chart, в качестве преемника расширения Graph. Он будет обрабатывать большинство простых случаев визуализации данных в статьях Википедии. Новый инструмент будет построен таким образом, чтобы в дальнейшем было легко добавить поддержку для большего количества случаев использования, если Фонд или разработчики сообщества захотят это сделать. Мы узнаем, что добились успеха, когда редакторы станут конвертировать старые графики с помощью нового инструмента.

В годовом плане 2024–2025 проект Charts записан в качестве ключевого результата Wiki Experiences 3.3.

График развертывания

The extension will be rolled out to wikis incrementally. It is already available on a select list of pilot wikis. The focus for the next wave of availability will be on the remaining Wikipedias. The rollout will start with most Wikipedias, moving then to ones that were heavy Graph users, and ending with some of the largest ones. These dates are subject to change as we track issues and monitor system performance during the rollout.

Стратегия

• Аудитория. Мы руководствуемся нуждами читателей Википедии. Мы сфокусируемся на наиболее частых случаях использования визуализации данных с целью обогатить энциклопедический контент. Это означает, что использование диаграмм вне статей (например, для PageViews) сейчас не является приоритетным. Однако несмотря на то, что основной фокус будет на статьях Википедии, использование диаграмм не будет ограничено страницами в основном пространстве и также будет доступно не-википедийным проектам.
• Ease of use. We want to make it easy for any editor to be able to create a chart intuitively. Previously, it was fairly difficult to add and edit graphs. Editors needed to be comfortable interacting with Vega, the underlying software powering graphs. This is why editors created most graphs using templates that contained pre-defined Vega code. Templates are more user-friendly, but cannot be easily reused across wikis. This time, different types of charts will be defined by the tool and will be available across all wikis. Editors will be able to add charts using a familiar wikitext format and will not need technical knowledge about the software underneath. These changes will reduce the need to rely on templates. They will also make it possible to upgrade the underlying library without disrupting existing charts.
• Architecture. Charts will be rendered (turned from code into visual content) on the Wikimedia Foundation servers using an open-source data visualization library, generated from data pulled from defined sources. More specifically:
  • Rendering charts on our servers will allow for pages to be loaded quickly. It also avoids the security issues that we faced with the graph extension. It will also enable charts to appear on the mobile apps, in exports, and in other reuse/offline scenarios.
  • For data visualization, charts will be generated using an open-source library. This library must meet our requirements like support for different languages, some level of interactivity, color customization, and more.
  • At first, there will be a single data source for charts: pages in the Data namespace on Wikimedia Commons. This will make it easy to reuse data between charts, avoiding the clutter of having the data inlined in wikitext. We will also design the system to support adding more data sources in the future.
• Поддержка редактора This project will only succeed if editors convert existing graph code to charts and start creating new charts. We will find ways to support editors with converting existing graphs through automated and manual processes. We will also look for ways to preserve existing graphs that are unlikely to be converted to charts. This may mean replacing them with static images or transitioning their use case to other tools.

What is the timeline of the project?

The Chart extension is now available on all Wikimedia wikis. This project is part of the FY24-25 annual plan and will conclude at the end of June 2025.

Which library will be used to render charts?

The Chart extension currently uses the Apache eCharts library. However, if there are unresolvable issues with eCharts, there is the possibility of switching to Vega (the library previously used for the Graphs extension). There is also the possibility of using eCharts for most chart types, but using a different library for certain specific chart types if it turns out to be much better than eCharts.

For details on why eCharts was chosen, and why Vega is considered the only reasonable alternative, see T368336#9971574.

What types of charts will be supported?

There will initially be a limited set of supported chart types: line, area, bar, and pie charts. The latest documentation is available on Расширение:Диаграммы page.

Where will chart definitions be stored? Where do I go if I want to edit a particular chart?

Chart definitions will live on their own .chart pages on Commons, under the Data: namespace. Charts will be treated as a standalone content type, rather than just as part of an article. It will be easy to reuse the same chart across wikis, and beyond Wikimedia platforms by making them available as links. Editors who want to embed charts in an article will be able to do so with a short piece of wikitext, similar to including an image from Commons, without needing to interact with complex templates.

One weakness of requiring that the data come from Commons tabular data is that data sourcing flows such as from MediaWiki APIs or Wikidata Query Service are not handled. While those sources are not the focus for this project, this project aims to design the extension in a way that they can be supported in the future.

How can volunteers add more chart types?

Once the initial infrastructure exists to create charts, technical volunteers will be welcome to contribute more chart types. In the meantime, you are encouraged to tell the developers what you think – which types of charts are most important to add next.

What will happen with the existing graphs?

For now, the existing graphs will remain in their current state. Some wikis have chosen to hide graphs entirely while others render a message explaining that graphs are disabled. Once it's possible to create charts that can replace graph uses, Chart extension developers will work with volunteers to start converting them so that readers can start to see them again.

It is unlikely that all graphs will be able to be converted to charts. For graphs that cannot be converted, it may be more beneficial to either: find an alternative tool to recreate the graph, convert the graph to a static image, or remove the graph altogether.

How to produce the charts efficiently?

There are several conceivable methods to semi-automatically produce and edit the charts and their tabular data:

• The script graphDataImport can be used in the web browser to extract data from existing graph wikicode, and convert it to a .tab page, and a .chart definition page.
• Generative AI can be prompted to extract data from existing graph wikicode and tables, and convert it to .tab and .chart pages and generate new wikicode, according to given specifications. It can also provide translation of titles, and be utilized to extend and update the .tab page with new data.
• The gadget TabularImportExport can convert Excel and .csv files to and from the .tab pages. You can activate it via your Commons preferences.
• The JSON "edit as table" user interface (part of the Jsonconfig extension) is available from the .tab edit page.
• Some bots potentially can periodically import statistics from the web, or from existing Wikipedia graphs, to .tab or .chart pages, upon request. Such bots include GraphBot (which can import existing {{Graph:chart }} wikicode in English Wikipedia), DPLA bot and SLiuBot.

What templates and modules are available?

It should be possible to use extension:chart without a multitude of local templates and modules. However, here are some templates and modules that are related to this extension:

• en:Template:Chart.
• de:Template:Chart
• commons:Category:Chart transform modules
