Gapminder_df = gapminder.query("continent = 'Oceania'") gdpPercap iso_alpha iso_numĠ Afghanistan Asia 1952. print(gapminder.head()) Output country continent year. We can get the insides of a dataset by the head() – function.Here’s an example of a Colour encoded column Plot with the Gapminder dataset – which comes built-in! – showing year vs life expectancy by the continent for Oceania: Built-In dataset from Plotly gapminder = px.data.gapminder() You can try playing around with these numbers to change the tilt.We can colour our points with the “color argument” in line() – method and px take care of the details, assign default colours and set up the legend etc. We have used the carto-darkmatter style from Mapbox, and we have set the pitch and bearing to provide a tilt to the map. All rows having the same value of dt_str will be a part of the same frame. Here, we have used the dt_str column to separate one frame from another. #Trim and sort data date1 = datetime(2020,3,1) date2 = datetime(2020,3,10) df = df >= date1) & (df <= date2)] df.sort_values(by =, inplace=True) df=df.apply(lambda x: x/500)įinally, we are now in a good shape to generate the visualization: fig = px.scatter_mapbox(df, lat="start_lat", lon="start_lon", hover_name="day", hover_data=, color_discrete_sequence=, zoom=3, height=550, width=500, animation_frame="dt_str", size='n_trip_scaled',size_max=10,) fig.update_layout( mapbox_style="carto-darkmatter") #Adjust pitch and bearing to adjust the rotation fig.update_layout(margin=, mapbox=dict( pitch=60, bearing=30 )) fig.show() Further, we will scale the n_trip_on field, which will indicate the size of the circles in the scatter visualization. Chart-studio doesn’t allow you to upload visualizations more than approx. We are doing this to limit the size of the visualization. Next, let’s limit the data to just 10 days. This is because a plotly animation requires the frames to be grouped by a string object.
We have performed some basic processing on the day column, and also created a dt_str column which contains the date in a more readable string format. We will use the same dataset that we used for the Cartopy tutorial: df = pd.read_csv('data/scatter_dummy_data.csv') df = pd.to_datetime(df,format="%d-%m-%Y") df = df.apply(lambda x: x.strftime("%d-%b-%Y")) You can skip this part if you are not interested in uploading your visualization to chart-studio.
#Plotly scatter free
Please note that the visualizations you upload to chart-studio using a free account will be public. Once that is done, get your user-name and api-key and add them to the set_credentials_file method above. You will need to sign-up for a free account on chart-studio.
Once the visualization is on chart_studio, you can get an embed link to directly integrate the visualization in-line on your website. This will help us upload our visualization directly to chart_studio.

In this tutorial, the installation of Plotly and the concepts covered in the Plotly tutorial will not be repeated.Īlso, you are strongly encouraged to go through the ‘About Mapbox’ section in the Interactive Choropleth visualization tutorial. It is very strongly recommended that you go through the Plotly tutorial before going through this tutorial.
If you are not familiar with python but have some experience of programming in some other languages, you may still be able to follow this tutorial, depending on your proficiency. This tutorial assumes that you are familiar with python and that you have python downloaded and installed in your machine. The tutorial is structured into the following sections:
