Hi, we’re Plotly…

We brought interactive, scientific data visualization to your Web browser.

Plotly creates and stewards the leading open-source data visualization and app building libraries for ML, data science, engineering, and the sciences. Downloaded over 100 million times, our libraries support engineers and scientists publishing charts and analytics apps to the Web in Python.

Our Story

We started our careers running the data science program for a California-based cleantech company, where we often needed to solve a seemingly simple problem: gather data, make sense of it, and share the results with others. On the surface it seemed straightforward, but after the collecting, analyzing, sorting, and other work were done, we were still left with important questions to answer:

🧐How do we share what we’ve learned with others in a meaningful way?

🧐How do we enable others to explore our data?

🧐Can we give others access to the models to explore on their own?

As we tried to address these questions, a more fundamental concern came to mind:  how can businesses make meaningful use of data science, if its use and understanding are restricted to just a few individuals?

This was the seed that started Plotly.

When we first started developing our technology, the tools for scientific and data analysis simply were not keeping pace with business needs. In our quest to make data and knowledge sharing more accessible, we focused on promoting the use of technology in these ways:

computer gear motivation

Use the web as a data science platform.

We focused on the most commonly used platform to enable sharing of complex data and models. By making it easy for data scientists to create, design, and build web interfaces for complex data and models, end users could interface with data interactively and online in any web browser.

Power discovery with open source.

We are firm believers in the power of the open-source community and the innovation that results from sharing and community development. For data science to keep pace with business needs, we focused on developing a core technology that is open-source and free, enabling greater sharing and faster innovation.


Provide unlimited flexibility.

As global coding literacy has increased, particularly the growth of Python and R, code-based analyses are supplanting that of point-and-click software for everything from data analysis and exploration to complex AI and Machine Learning models. Our solution would build on these flexible coding environments and enable businesses to go farther, faster.

Remove language as a barrier.

Language agnostic coding tools prevent duplicate effort and accelerate innovation. We aim to create software that enables developers, data scientists, and quants everywhere to use the coding tools of their choice.

Enable shared goals across the organization.

Business groups, Data Science, and Tech teams need to align and have a common language and data platform. At Plotly, we develop software that’s designed to enable data scientists, analysts and technical teams to work hand-in-hand with business teams, giving everyone in a company direct access to data and models.

So that is what we are doing!

We hope that you’ll join us.

Plotly Land Acknowledgement

Plotly is located on Tioh’tia:ke, commonly known in English as Montreal Island, in Kanien’kehá:ka, the “Place of the People of the Flint” (the Kanien’kéha). The Kanien’kéha are members of the Rotinonshon:ni (Haudenosaunee), the Confederacy of the Completed Longhouse. The Rotinonshon:ni consists of the Six Nations: The Onöndowága (Seneca, the Keepers of the Western Door), the Gayogohó:no’ (Cayuga), the Onöñda’gega’ (Onondaga), the Onyota’a:ka (Oneida), the Kanien’kéha (Mohawk, the Keepers of the Eastern Door), and the Skarū‘ren’ (Tuscarora). The lands of the Rotinonshon:ni extended throughout much of what is colonially determined New York state, southern Quebec, and parts of southern Ontario. These lands, which were never ceded by treaty, were forcibly seized by white settlers, missionaries, police, and armies. Despite this, the Rotinonshon:ni still live in the area around Plotly, with the Kanien’kéha communities of Kahnawake and Kanatasake close by and many Rotinonshon:ni people living in Montreal as well.

Although Plotly is located on Tioh’tia:ke, we work with clients and colleagues across the globe. We encourage every non-Indigenous settler to learn more about the land they are occupying by visiting Whose Land, Native Land, and This Land I Stand. These organizations contribute an immense amount of research to recognizing Indigenous lands around the world and offer exemplar data visualizations depicting those places.

We at Plotly have a responsibility to fight for Rotinonshon:ni self-determination against ongoing American and Canadian colonialism and for inclusivity and diversity in the tech industry. Plotly is interested in improving this space and making it more accessible to people from different cultures, as well as using and encouraging the use of our technology for anti-racist efforts.

For those interested in getting involved, you can contribute to groups including Natives in Tech, Center for Indigenous Innovation & Technology, and First Nations Technology Council. Locally in Tioh’tia:ke, you can donate to groups such as the Native Women’s Shelter of Montreal or the Native Friendship Centre of Montreal.
