With the explore
command you can open your dataset in Visidata which is an amazing visual tool for working with tabular data in Console. For example try "Shift+F" for creating data histograms!
pip install frictionless[visidata]
pip install frictionless[visidata,zenodo] # for examples in this tutorial
For example, let's expore this interesing dataset:
frictionless explore https://zenodo.org/record/3977957
Before entering Visidata, it's highly recommended to read its documentation:
You can get it in Console as well:

NAME
VisiData — a terminal utility for exploring and arranging tabular data
SYNOPSIS
vd [options] [input ...]
vd [options] --play cmdlog [-w waitsecs] [--batch] [-o output]
[field=value]
vd [options] [input ...] +toplevel:subsheet:col:row
DESCRIPTION
VisiData is an easy-to-use multipurpose tool to explore, clean, edit, and
restructure data. Rows can be selected, filtered, and grouped; columns
can be rearranged, transformed, and derived via regex or Python expres‐
sions; and workflows can be saved, documented, and replayed.
REPLAY MODE
-p, --play=cmdlog replay a saved cmdlog within the interface
-w, --replay-wait=seconds
wait seconds between commands
-b, --batch replay in batch mode (with no interface)
-o, --output=file save final visible sheet to file as .tsv
--replay-movement toggle --play to move cursor cell-by-cell
field=value replace "{field}" in cmdlog contents with value

~ # % $ @ z#
set type of current column to str/int/float/cur‐
rency/date/len
^ rename current column
g^ rename all unnamed visible columns to contents of se‐
lected rows (or current row)
z^ rename current column to combined contents of current
cell in selected rows (or current row)
gz^ rename all visible columns to combined contents of cur‐
rent column for selected rows (or current row)
= expr create new column from Python expr, with column names,
and attributes, as variables
g= expr set current column for selected rows to result of Python
expr
gz= expr set current column for selected rows to the items in
result of Python sequence expr
z= expr evaluate Python expression on current row and set
current cell with result of Python expr
i add column with incremental values
gi set current column for selected rows to incremental
values
zi step add column with values at increment step
gzi step set current column for selected rows at increment step
' (tick) add a frozen copy of current column with all cells eval‐
uated
g' open a frozen copy of current sheet with all visible
columns evaluated
z' gz' add/reset cache for current/all visible column(s)
: regex add new columns from regex split; number of columns
determined by example row at cursor
; regex add new columns from capture groups of regex (also
requires example row)
z; expr create new column from bash expr, with $columnNames as
variables
* regex/subst add column derived from current column, replacing regex
with subst (may include \1 backrefs)
g* gz* regex/subst
modify selected rows in current/all visible column(s),
replacing regex with subst (may include \1 backrefs)
( g( expand current/all visible column(s) of lists (e.g. [3])
or dicts (e.g. {3}) one level
z( gz( depth expand current/all visible column(s) of lists (e.g. [3])
or dicts (e.g. {3}) to given depth (0= fully)
) unexpand current column; restore original column and re‐
move other columns at this level
zM row-wise expand current column of lists (e.g. [3]) or
dicts (e.g. {3}) within that column
Row Selection
s t u select/toggle/unselect current row
gs gt gu select/toggle/unselect all rows
zs zt zu select/toggle/unselect all rows from top to cursor
gzs gzt gzu select/toggle/unselect all rows from cursor to bottom
| \ regex select/unselect rows matching regex in current column
g| g\ regex select/unselect rows matching regex in any visible
column
z| z\ expr select/unselect rows matching Python expr in any visible
column
, (comma) select rows matching display value of current cell in
current column
g, select rows matching display value of current row in all
visible columns
z, gz, select rows matching typed value of current cell/row in
current column/all visible columns
Row Sorting/Filtering
[ ] sort ascending/descending by current column; replace any
existing sort criteria
g[ g] sort ascending/descending by all key columns; replace
any existing sort criteria
z[ z] sort ascending/descending by current column; add to ex‐
isting sort criteria
gz[ gz] sort ascending/descending by all key columns; add to ex‐
isting sort criteria
" open duplicate sheet with only selected rows
g" open duplicate sheet with all rows
gz" open duplicate sheet with deepcopy of selected rows
The rows in these duplicated sheets (except deepcopy) are references to
rows on the original source sheets, and so edits to the filtered rows
will naturally be reflected in the original rows. Use g' to freeze sheet
contents in a deliberate copy.

a za append blank row/column; appended columns cannot be
copied to clipboard

clipboard (using options.clipboard_copy_cmd)

determined by extension (default .tsv)
Note: if the format does not support multisave, or the
filename ends in a /, a directory will be created.
z^S filename save current column only to filename in format
determined by extension (default .tsv)
^D filename.vdj save CommandLog to filename.vdj file
A open new blank sheet with one column
T open new sheet that has rows and columns of current
sheet transposed
+ aggregator add aggregator to current column (see Frequency Table)
z+ aggregator display result of aggregator over values in selected
rows for current column; store result in Memory Sheet

add column where each row contains a list of that row,
nBefore rows, and nAfter rows
Data Visualization
. (dot) plot current numeric column vs key columns. The numeric
key column is used for the x-axis; categorical key column
values determine color.
g. plot a graph of all visible numeric columns vs key
columns.
If rows on the current sheet represent plottable coordinates (as in .shp
or vector .mbtiles sources), . plots the current row, and g. plots all
selected rows (or all rows if none selected).

FILES
At the start of every session, VisiData looks for $HOME/.visidatarc, and
calls Python exec() on its contents if it exists. For example:
options.min_memory_mb=100 # stop processing without 100MB free
bindkey('0', 'go-leftmost') # alias '0' to go to first column, like vim
def median(values):
L = sorted(values)
return L[len(L)//2]
vd.aggregator('median', median)
Functions defined in .visidatarc are available in python expressions
(e.g. in derived columns).
SUPPORTED SOURCES
Core VisiData includes these sources:
tsv (tab-separated value)
Plain and simple. VisiData writes tsv format by default. See the
--tsv-delimiter option.
csv (comma-separated value)
.csv files are a scourge upon the earth, and still regrettably
common.
See the --csv-dialect, --csv-delimiter, --csv-quotechar, and
--csv-skipinitialspace options.
Accepted dialects are excel-tab, unix, and excel.
fixed (fixed width text)
Columns are autodetected from the first 1000 rows (adjustable with
--fixed-rows).
json (single object) and jsonl/ndjson/ldjson (one object per line).
Cells containing lists (e.g. [3]) or dicts ({3}) can be expanded
into new columns with ( and unexpanded with ).
sqlite
May include multiple tables. The initial sheet is the table
directory; Enter loads the entire table into memory. z^S saves
modifications to source.
URL schemes are also supported:
http (requires requests); can be used as transport for with another
filetype
For a list of all remaining formats supported by VisiData, see
https://visidata.org/formats.
In addition, .zip, .gz, .bz2, .xz, ,zstd, and .zst files are decompressed
on the fly.
