## Plotly  Plotly is a collaborative data analysis and graphing tool. Plotly lets you access, analyze, and visualize data. Instead of collaborating by emailing a data set, script, graphs, screenshots, and explanations to your team, Plotly lets you work with others online, commenting on projects and saving revisions. Plotly also pairs data and graphs. Pairing graphs and the relevant data like this solves a real problem; a [recent study](www.scientificamerican.com/podcast/episode.cfm?id=where-have-all-the-data-gone-13-12-19) showed that, twenty years after publication in 1991, 80 percent of data used in scientific papers was no longer available. _Solution_. Plotly hosts data, code, and graphs together, and lets you fork your own versions (see _e.g.,_ [this Washington Post article](http://www.washingtonpost.com/blogs/wonkblog/wp/2013/06/14/do-low-taxes-on-the-rich-leave-the-middle-class-with-lower-wages/)).   **How it works.** Plotly offers a) a graphing GUI with bubble charts, box plots, line charts, area charts, scatter plots, histograms, 2D histograms, heatmaps, log axes, error bars, date axes, multiple axes, subplots, and insets insets,  b) [Plotly APIs](Plot.ly/api) [APIs](Plot.ly/api)  for Python, R, MATLAB, REST, Julia, Arduino, and Perl, c) a Python sandbox and support for NumPy, LaTeX, pandas, datetime, and [IPython Notebook](nbviewer.ipython.org/github/plotly/IPython-plotly/tree/master/) support, d) a grid with fits, functions, stats, ANOVAs, and more. ## Authorea  Authorea is a tool to write research documents in collaboration. The post you are reading was written in Authorea! Collaborating on scholarly papers with a mix of emailed documents, drafts, lost revisions, and comments is inefficient and painful. Authorea puts the whole publication tookit online: an interactive GUI, revision history, comments, and beautiful rendering for LaTeX, images, and graphs. Importantly, Authorea now allows seamless and easy inclusion of Plotly graphs. Here's how.
